Metabolite Identification
Common NameL-Lactic acid
DescriptionL-Lactic acid, also known as D-lactate or D-milchsaeure, belongs to the class of organic compounds known as alpha hydroxy acids and derivatives. These are organic compounds containing a carboxylic acid substituted with a hydroxyl group on the adjacent carbon. L-Lactic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. L-Lactic acid exists in all living species, ranging from bacteria to humans. L-Lactic acid participates in a number of enzymatic reactions, within cattle. In particular, L-Lactic acid can be converted into pyruvic acid; which is catalyzed by the enzyme L-lactate dehydrogenase. In addition, L-Lactic acid can be converted into L-lactic acid through the action of the enzyme monocarboxylate transporter. In cattle, L-lactic acid is involved in the metabolic pathway called cancer (via the Warburg effect). L-Lactic acid is a potentially toxic compound.
