L-Lactic acid is the optically active form of lactic acid and has an (S) stereochemical arrangement. Animals produce L-Lactate, conjugate base of lactic acid, from pyruvate via lactate dehydrogenase in fermentation during normal metabolism and exercise. Lactic acid bacteria perform lactic acid fermentation, converting carbohydrates to lactic acid. In humans, lactic acid and its conjugate base are part of many biological processes from prenatal development to extracellular fluid surrounding neurons.
Lactic acid is used in food preparation to produce specific types of beer and other alcoholic beverages. When used in the colon it prevents gastrointestinal fermentation, and in an 8% cream has been used on photodamaged skin. Polylactic acid can be formed when two molecules of lactic acid are dehydrated and then catalyzed into a plastic that is both biodegradable and not derived from petrochemicals. It is also used by detergent manufacturers due to its anti-bacterial properties, and can be used to produce water-soluble lactates from otherwise insoluble active ingredients.
