Metabolite Identification
Common Name2-Oxovaleric acid
Description2-Oxovaleric acid, also known as 2-oxovalerate or a-ketovalerate, 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. 2-Oxovaleric acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, 2-Oxovaleric acid has been detected, but not quantified in, herbs and spices. This could make 2-oxovaleric acid a potential biomarker for the consumption of these foods.
