Metabolite Identification
Common Name2-Oxo-3-hydroxy-4-phosphobutanoic acid
Description2-Oxo-3-hydroxy-4-phosphobutanoic acid, also known as (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate or alpha-keto-3-hydroxy-4-phosphobutyrate, 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-Oxo-3-hydroxy-4-phosphobutanoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Oxo-3-hydroxy-4-phosphobutanoic acid exists in all living species, ranging from bacteria to humans. Outside of the human body, 2-Oxo-3-hydroxy-4-phosphobutanoic acid has been detected, but not quantified in, several different foods, such as peanuts, breakfast cereals, kai-lans, common beans, and cardoons. This could make 2-oxo-3-hydroxy-4-phosphobutanoic acid a potential biomarker for the consumption of these foods. A 2-oxo monocarboxylic acid that is 2-oxobutanoic acid which is substituted by a phosphonooxy group at position 4 and a hydroxy group at the 3-pro-R position.
