Metabolite Identification
Common NameL-Malic acid
Description(S)-Malic acid, also known as malate or L-apple acid, 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 (S)-Malic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule (S)-Malic acid exists in all eukaryotes, ranging from yeast to humans.
