Extended data:

Lactic acid (IUPAC scientific name: 2- hydroxypropionic acid) is a compound that plays a role in many biochemical processes. It is a carboxylic acid with the molecular formula C3H6O3. It is a carboxylic acid containing hydroxyl groups, so it is an α -hydroxy acid (AHA). In aqueous solution, its carboxyl group releases a proton to produce lactate ion CH3CHOHCOO? . Lactate dehydrogenase converts pyruvate into L- lactic acid during fermentation. Lactic acid is constantly produced in general metabolism and exercise, but its concentration generally does not rise.
