how many valence electrons does lactic acid havehow many valence electrons does lactic acid have

They are typically the electrons with the highest value of the principal quantum number, n. Another way to think of valence electrons is that they are the outermost electrons in an atom, so they are the most susceptible . Direct link to Rita Rose Marsh's post What effect does the lact, Posted 4 years ago. how many protons are in lactic acid (c3h6o3)? Score: 4.9/5 (8 votes) . In 2006, global production of lactic acid reached 275,000 tonnes with an average annual growth of 10%.[17]. Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. Describe how bacteria, including those we employ to make yogurt, make ATP in the absence of oxygen. One of them for example was the French chemist Joseph Louis Gay-Lussac, who was especially interested in fermentation processes, and he passed this fascination to one of his best students, Justus von Liebig. The process of fermentation limits the amount of lactose available. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. Different types of LAB will produce different types of silage fermentation, which is the fermentation of the leafy foliage. Do you consider yourself a sprinter or a long distance runner? this is possible because carbon can. The CO generated in this step is utilized again and exposed to surplus steam to attain CO 2 and more H 2. To determine the valence electrons of HNO 3, it is first necessary to know the valence electrons of the hydrogen, nitrogen, and oxygen atoms. Exclude groups 3 through 12. Other products, like industrial yogurt, coming mainly from China and western countries, have tended to replace it more and more, mainly in urban areas. (b) Oxygen has valence electrons and makesbond(s) in compounds. d.valence electrons are shared between oxygen atoms. Lactic acid is hygroscopic. What 4 types of bonds can carbon form? Brewers of more common beer styles would ensure that no such bacteria are allowed to enter the fermenter. It is because of the dominance of this mutation that Western cultures believe it is unusual to have a lactose intolerance, when it is in fact more common than the mutation. In computer science, ACID (atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. This oxygen brought in six Valence electrons. Or between the two types of runners? Atomic number Elements Valence electrons; 1: Hydrogen (H) 1: 2: Helium (He) 2: 3: Lithium (Li) 1: 4: Beryllium (Be) 2: 5: SO42-. If you run marathons, you probably have more red oxidative fibers, performing aerobic respiration. It was once thought that the accumulation of lactate in muscles was responsible for soreness caused by exercise, but recent research suggests this is probably not the case. After cooling the wort, yeast and bacteria are allowed to fall into the open fermenters. [27], Some evidence suggests that lactate is important at early stages of development for brain metabolism in prenatal and early postnatal subjects, with lactate at these stages having higher concentrations in body liquids, and being utilized by the brain preferentially over glucose. Direct link to Rachel's post In the diagrams there wri, Posted 3 years ago. In yeast, the anaerobic reactions make alcohol, while in your muscles, they make lactic acid. These four genera are able to be separated from each other by using biochemical testing, and simple biological tests are readily available. In some Asian cuisines, fish is traditionally fermented with rice to produce lactic acid that preserves the fish. [1][16], As in yoghurt, when the acidity rises due to lactic acid-fermenting organisms, many other pathogenic microorganisms are killed. It finds further use in topical preparations and cosmetics to adjust acidity and for its disinfectant and keratolytic properties. a. During glycolysis, one glucose molecule is converted to two pyruvate molecules, producing two net ATP and two NADH. Explanation: Helium is located in period 1, group 18 of the Periodic Table and has an atomic number equal to 2. [21], Another change to the lactic acid hypothesis is that when sodium lactate is inside of the body, there is a higher period of exhaustion in the host after a period of exercise. Lactic acid is also found in fermented dairy and meats, but vegans . The remaining #2# valence electrons will be placed as lone pairs on the nitrogen atom, ensuring its complete octet. In 1808, Jns Jacob Berzelius discovered that lactic acid (actually L-lactate) also is produced in muscles during exertion. Example: Consider the Lewis structure for sulfur tetrafluoride (SF 4) which contains 34 valence electrons. In which of the following sets is the symbol of the element, the number of protons, and the number of electrons given correctly? What are some common mistakes students make when drawing Lewis structures? Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. It is also possible to encounter a molecule that seems to have too many valence electrons. hold You may have notice this type of fermentation in your own muscles, because muscle fatigue and pain are associated with lactic acid. In the figure, how many unpaired electrons does phosphorus have in its valence shell? [29][30] Because of this local metabolic activity of glial cells, the extracellular fluid immediately surrounding neurons strongly differs in composition from the blood or cerebrospinal fluid, being much richer with lactate, as was found in microdialysis studies. Average mass 89.093 Da. Direct link to Revan Rangotis's post Okay, this is actually re, Posted 5 years ago. Valence electrons are those found in the outermost orbital of an atom. Apart from whole-sequence genomics, common tests include H2S production, motility and citrate use, indole, methyl red and Voges-Proskauer tests.[9]. [citation needed], Milk products and their fermentation have had an important influence on some cultures development. In solution, it can ionize by loss of a proton to produce the lactate ion CH3CH(OH)CO2. So it has a minus one formal charge. Eliezrie, Inc., manufactures and sells two products: Product G8 and Product O0. Since there is a limited supply of NAD\(^+\) available in any given cell, this electron acceptor must be regenerated to allow ATP production to continue. Chemical analysis of archeological finds show that milk fermentation uses predate the historical period; its first applications were probably a part of the Neolithic Revolution. Why can't human undergo ethanol fermentation? Lactic acid is an organic acid. Transcribed image text: NH2CH2CO2H glycine 1. number of valence electrons: Lewis Structure Molecular Geometry Drawing 2. central atom (s): 5. molecular geometry: 3. The problem of these first farmers was that fresh milk is nearly indigestible by adults, so they had an interest to discover this mechanism. Hydrogen bonds form with itself and other polar molecules. Bases can be thought of as the chemical opposite of acids. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells. 1. . Data concerning the expected production of each product and the expected total direct labor-hours (DLHs) required to produce that output appear below: Copy. Remember that an element's electron cloud will become more stable by filling, emptying, or half-filling the shell. [10][18], For a probiotic yogurt, additional types of bacteria such as Lactobacillus acidophilus are also added to the culture.[18]. During this time, he worked at the University of Lille, where a local distillery asked him for advice concerning some fermentation problems. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. The Lewis Structure also shows that it is a polar molecule since all of the electrons are not evenly distributed. What kinds of organisms use anaerobic cellular respiration? During power exercises such as sprinting, when the rate of demand for energy is high, glucose is broken down and oxidized to pyruvate, and lactate is then produced from the pyruvate faster than the body can process it, causing lactate concentrations to rise. The bacteria produce lactic acid, as well as simple alcohols and other hydrocarbons. ABSTRACT The biodegradable, aliphatic polyester poly(lactic acid), PLA . The third shell contains seven electrons. Lactic acid fermentation is the type of anaerobic respiration carried out by yogurt bacteria (Lactobacillus and others) and by your own muscle cells when you work them hard and fast. Per chance and with the badly equipped laboratory he had at that time, he was able to discover that in this distillery, two fermentations were taking place, a lactic acid one and an alcoholic one, both induced by microorganisms. Valence electrons are the electrons located in an atom's outermost shell. Lactic Acid | HC3H5O3 or C3H6O3 | CID 612 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities . Even though Pasteur described some concepts that are still accepted today, Liebig refused to accept them. It is said to occupy orbitals in an atom. Image of tanks used for wine production by fermentation of grapes. To find formal charges in a Lewis structure, for each atom, you should count how many electrons it "owns". Production includes both artificial synthesis as well as natural sources. Recall that glycolysis breaks a glucose molecule into two pyruvate molecules, producing a net gain of two ATP and two NADH molecules. Lactic acid is a substance that builds up in muscles during exercise and makes them ache. If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen. It is associated with damage to the muscle fibers, but the details don't appear to be well studied. Posted 7 years ago. In contrast, 36 ATP molecules can be generated per molecule of . However, there is more to this question than meets the eye. . Muscle cells also carry out lactic acid fermentation, though only when they have too little oxygen for aerobic respiration to continuefor instance, when youve been exercising very hard. Calculate the total electrons and determine the valence shell. Lactic acid producing bacteria also act as a protective barrier against possible pathogens such as bacterial vaginosis and vaginitis species, different fungi, and protozoa through the production of hydrogen peroxide, and antibacterial compounds. These bonds will account for #6# of the molecule's #26# valence electrons. In lists of nutritional information lactic acid might be included under the term "carbohydrate" (or "carbohydrate by difference") because this often includes everything other than water, protein, fat, ash, and ethanol. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Across the suborbital, the electronic configuration of chlorine is 1s 2 2s 2 2p 6 3s 2 3p 5. Alcohol fermentation has two steps: glycolysis and NADH regeneration. Each new period begins with one valence electron. A valence electron is the total number of electrons found in a valenceshell. It is most commonly used for fluid resuscitation after blood loss due to trauma, surgery, or burns. - 1 of 1 defined stereocentres. By putting the two electrons together on the same side, we emphasize the fact that these two electrons are both in the 1s subshell; this is the common convention we will adopt, although there will be exceptions later. 3. Count all of its lone pair electrons, and half of its bonding electrons. [2] When in the dissolved state, it forms a colorless solution. Lactate, which is just the deprotonated form of lactic acid, gives the process its name. Are Drumsticks and Athletic Prowess Related? Too Many Electrons . If you want a Periodic table with Valence electrons, then visit Periodic table with Valence electrons labeled in it. The purpose of these festivities is to "close" the past year clean the house or the yurt, honor the animals for having provided their food, and prepare everything for the coming summer season to be ready to "open" the new year. It is shown below: Step 1: Determine the valence electrons of hydrogen, nitrogen, and oxygen atoms. (Where you will get the HD images along with the explanation). During NADH regeneration, the two pyruvate molecules are first converted to two acetaldehyde molecules, releasing two carbon dioxide molecules in the process. [10][11] The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. [15], Lactic acid fermentation is also used in the production of sauerkraut. [27] It was also hypothesized that lactate may exert a strong action over GABAergic networks in the developing brain, making them more inhibitory than it was previously assumed,[31] acting either through better support of metabolites,[27] or alterations in base intracellular pH levels,[32][33] or both. Some prokaryotesbacteria and archaeathat live in low-oxygen environments rely on anaerobic respiration to break down fuels. Atoms are most stable if they have a filled valence shell . Note that the + sign in the Lewis structure for H3O+ means that we have lost a valence electron. Count all the valence electrons for each atom. Very important with often a traditional meaning as well are fermentation products of mare milk, like for example the slightly-alcoholic yogurt kumis. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. For example, some archaea called methanogens can use carbon dioxide as a terminal electron acceptor, producing methane as a by-product. One is known as L -lactic acid, ( S )-lactic acid, or (+)-lactic acid, and the other, its mirror image, is D -lactic acid, ( R )-lactic acid, or ()-lactic acid. In winemaking, a bacterial process, natural or controlled, is often used to convert the naturally present malic acid to lactic acid, to reduce the sharpness and for other flavor-related reasons. The atomic number for nitrogen is 7. So it's formal charges. DL-Lactic acid is miscible with water and with ethanol above its melting point, which is about 16 to 18C (61 to 64F). There are a few reasons that spring to mind. PLA is an example of a plastic that is not derived from petrochemicals. [20] Lactic acid producing bacteria can be divided in two classes: homofermentative bacteria like Lactobacillus casei and Lactococcus lactis, producing two moles of lactate from one mole of glucose, and heterofermentative species producing one mole of lactate from one mole of glucose as well as carbon dioxide and acetic acid/ethanol. it has four valence electrons. Accessibility StatementFor more information contact us [email protected] check out our status page at https://status.libretexts.org. The PH3 Lewis structure has 8 valence electrons. [12][13][14], Kimchi also uses lactic acid fermentation. Answer to. Arsenic has 33 electrons around its nucleus, 5 of which are valence electrons on the outermost orbital. Lactic acid is also responsible for the sour flavor of sourdough bread. This one once seven has won more than it brought in. For chicken or turkey dinners, do you prefer light meat or dark? Direct link to Phil Rattazzi's post Is there a reason why Flo, Posted 6 years ago. A valence electron is an electron that is the most likely to be involved in a chemical reaction. What is an example of a Lewis structures practice problem? The main takeaway is that neither lactic acid nor lactate ions are responsible for the soreness you feel 12-72 hours after a workout. Use this method to predict the charges of ions in Ionic compounds a step! The other atom has a pH 4 solution would have 9.0 * 10^-5 mol/L of H+ ions acids! It is found in small quantities in the Earth's crust and is thought to have properties that are both beneficial and harmful to human health. What are some common mistakes students make with Lewis structures? [6] It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal, which is governed by a number of factors, including monocarboxylate transporters, concentration and isoform of LDH, and oxidative capacity of tissues. Muscle cells and red blood cells make the most lactic acid, but it can come from any tissue in your body. Answer. ", "NNFCC Renewable Chemicals Factsheet: Lactic Acid", Ullmann's Encyclopedia of Industrial Chemistry, "In vivo evidence for lactate as a neuronal energy source", "Lactate metabolism: a new paradigm for the third millennium", "Energy substrate availability as a determinant of neuronal resting potential, GABA signaling and spontaneous network activity in the neonatal cortex in vitro", "Depolarizing actions of GABA in immature neurons depend neither on ketone bodies nor on pyruvate", "Spontaneous network events driven by depolarizing GABA action in neonatal hippocampal slices are not attributable to deficient mitochondrial energy metabolism", "Questioning the depolarizing effects of GABA during early brain development", "Lactate Effectively Covers Energy Demands during Neuronal Network Activity in Neonatal Hippocampal Slices", "Reduction of oxaluria after an oral course of lactic acid bacteria at high concentration", "USDA National Nutrient Database for Standard Reference, Release 28 (2015) Documentation and User Guide", "Akebia: A Potential New Fruit Crop in China", "Current EU approved additives and their E Numbers", "Listing of Food Additives Status Part II", "Standard 1.2.4 Labelling of ingredients", "Listing of Specific Substances Affirmed as GRAS:Lactic Acid", "Agency Response Letter GRAS Notice No. The cells then default to fermentation, since they are in an anaerobic environment. Lithium is an alkali metal with the atomic number = 3 and an atomic mass of 6.941 g/mol. Direct link to Max Spencer's post To make vinegar, grapes a, Posted 7 years ago. [50] Lactic acid is produced commercially by fermentation of carbohydrates such as glucose, sucrose, or lactose, or by chemical synthesis. See explanation. It can also form different types of chains. Despite the common use of the term lactic acid in the literature, the byproduct of fermentation in animal cells is lactate. Direct link to markselden's post Is fermentation really al, Posted 3 years ago. Advertisement. Lactic acid containing bacteria have shown promise in reducing oxaluria with its descaling properties on calcium compounds.[39]. Consuming white food in this festive context is a way to connect to the past and to a national identity, which is the great Mongolian empire personified by Genghis Khan. The valence is a numerical characteristic of the ability of atoms of a given element to bond with other atoms. Legal. This means that lithium has 3 protons, 3 electrons and 4 neutrons (6.941 - 3 = ~4). A hydrogen sulfide molecule, "H"_2"S", contains two hydrogen atoms and . Industrial scale production of D-lactic acid by fermentation is possible, but much more challenging. If the pH in the vagina becomes too basic, more lactic acid will be produced to lower the pH back to a more acidic level. Lactic acid is used as a food preservative, curing agent, and flavoring agent. [18] These bacteria produce lactic acid in the milk culture, decreasing its pH and causing it to congeal. There are 8 valence electrons for the H3O+ Lewis structure. As a result, neutral helium will only have 2 electrons surrounding its nucleus. So once the use of ATP is included, the overall reaction is. Would you believe it has something to do with muscle color? The main type of bacteria used in the production of sauerkraut is of the genus Leuconostoc. a. This early habituation to lactose consumption in the first settler societies can still be observed today in regional differences of this mutation's concentration. The bacteria also produce compounds that give yogurt its distinctive flavor. [21], Racemic lactic acid is synthesized industrially by reacting acetaldehyde with hydrogen cyanide and hydrolysing the resultant lactonitrile. See answer. Lactic acid is produced industrially by bacterial fermentation of carbohydrates, or by chemical synthesis from acetaldehyde. Lactic acid is found primarily in sour milk products, such as kumis, laban, yogurt, kefir, and some cottage cheeses. A mixture of the two in equal amounts is called DL-lactic acid, or racemic lactic acid. Ethanol tolerance of yeast ranges from about. [10][18] The primary bacteria used are typically Lactobacillus bulgaricus and Streptococcus thermophilus, and United States as well as European law requires all yogurts to contain these two cultures (though others may be added as probiotic cultures). Zero Samos, This one. These lone pairs will account for another #3 xx 6 = 18# valence electrons. start text, O, end text, start subscript, 2, end subscript, left parenthesis, start text, S, O, end text, start subscript, 4, end subscript, start superscript, 2, minus, end superscript, right parenthesis, left parenthesis, start text, N, O, end text, start subscript, 3, end subscript, start superscript, minus, end superscript, right parenthesis, left parenthesis, start text, H, end text, start subscript, 2, end subscript, start text, S, end text, right parenthesis, start text, N, A, D, end text, start superscript, plus, end superscript, start superscript, 3, comma, 4, end superscript, start text, C, O, end text, start subscript, 2, end subscript. If you are familiar with grouse, you know that these birds "flush" with great speed over short distances. Direct link to LakinduD's post Anaerobic respiration in , Posted 5 years ago. During childbirth, lactate levels in the fetus can be quantified by fetal scalp blood testing. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. { "15.1:_Glycolysis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.2:_The_Citric_Acid_Cycle" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.3:_Lactic_Acid_Fermentation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.4:_The_Electron_Transport_Chain" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "15.E:_Metabolic_Cycles_(Exercises)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "9.2:_Homeostasis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_10:_Nuclear_and_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_11:_Properties_of_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_12:_Organic_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_13:_Amino_Acids_and_Proteins" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_14:_Biological_Molecules" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_15:_Metabolic_Cycles" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_1:_Measurements_and_Problem-Solving" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_2:_Elements_and_Ions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_3:_Compounds" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_4:_Structure_and_Function" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_5:_Properties_of_Compounds" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_6:_Energy_and_Properties" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_7:_Solids_Liquids_and_Gases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_8:_Properties_of_Solutions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "Chapter_9:_Equilibrium_Applications" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "Lactic Acid Fermentation", "showtoc:no", "license:ck12", "authorname:ck12" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FUniversity_of_Kentucky%2FUK%253A_CHE_103_-_Chemistry_for_Allied_Health_(Soult)%2FChapters%2FChapter_15%253A_Metabolic_Cycles%2F15.3%253A_Lactic_Acid_Fermentation, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Lactic Acid Fermentation: Muscle Cells and Yogurt.
