| Description | Gentisuric 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). |
