Metabolite Identification
Common NameAlpha-Hydroxyhippuric acid
DescriptionAlpha-Hydroxyhippuric acid, also known as alpha-hydroxybenzoylglycine or a-hydroxyhippate, belongs to the class of organic compounds known as hippuric acids. Hippuric acids are compounds containing hippuric acid, which consists of a of a benzoyl group linked to the N-terminal of a glycine. Alpha-Hydroxyhippuric acid (or Benzamidohydroxyacetic acid) is a carboxylic acid occasionally present in human biofluids. Alpha-hydroxyhippuric acid should not be confused with 2-hydroxyhippuric acid. It is used in the formulation of some herbicides and inks to enhance their action (Patents US 1996-657134, US 1975-627965). It is a substrate for the enzyme peptidyl-alpha-hydroxyglycine alpha-amidating lyase. Alpha-Hydroxyhippuric acid (or Benzamidohydroxyacetic acid) is a hippuric acid derivative that is occasionally present in human biofluids.
