Metabolite Identification
Common NameGentisuric acid
DescriptionGentisuric acid, also known as gentisate, 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. Gentisuric acid is a metabolite of aspirin in man. Gentisuric acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
