2-Oxo-3-hydroxy-4-phosphobutanoic acid

(R)-3-hydroxy-2-oxo-4-phosphonooxybutanoic acid is 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. It has a role as a mouse metabolite and an Escherichia coli metabolite. It is a secondary alpha-hydroxy ketone, a 2-oxo monocarboxylic acid, a 3-hydroxy monocarboxylic acid, an oxoalkyl phosphate, a hydroxyalkyl phosphate and a carboxyalkyl phosphate. It is functionally related to a butyric acid. It is a conjugate acid of a (R)-3-hydroxy-2-oxo-4-(phosphonatoooxy)butanoate.
