Metabolite Identification
Common NameMalic acid
DescriptionMalic acid, also known as malate or aepfelsaeure, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Malic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule. Malic acid exists in all living organisms, ranging from bacteria to humans. In cattle, malic acid is involved in the metabolic pathway called the transfer OF acetyl groups into mitochondria pathway.
