Chemical Information
FooDB Name(S)-2-Acetolactate
Description(S)-2-Acetolactate, also known as b-dyn a, belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms (S)-2-Acetolactate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (S)-2-Acetolactate exists in all living species, ranging from bacteria to humans. Outside of the human body, (S)-2-Acetolactate has been detected, but not quantified in, several different foods, such as european chestnuts, rosemaries, half-highbush blueberries, pineapples, and chinese water chestnuts. This could make (S)-2-acetolactate a potential biomarker for the consumption of these foods.
