Applications N-Benzoylglycine also known as Hippuric Acid is the glycine conjugate of benzoic acid commonly found in ruminant urine. Hippuric acid is synthesized in the liver and its production is greatly increased following consumption of benzoic acid. In itself it does not have a direct biological function, however p-hydroxy-hippurica acid can be used as an inhibitor of Ca2+ ATPase.A possible biomarker of Parkinson’s disease.
