Metabolite Identification

Common Name

xi-3-Hydroxy-2-oxobutanoic acid

Description

xi-3-Hydroxy-2-oxobutanoic acid, also known as 3-hydroxy-alpha-ketobutyrate or beta-hydroxy-alpha-oxobutyric acid, 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. xi-3-Hydroxy-2-oxobutanoic acid has been detected, but not quantified in, fruits and milk and milk products. This could make XI-3-hydroxy-2-oxobutanoic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on xi-3-Hydroxy-2-oxobutanoic acid.
