Common Name2-Methylhippuric acid
Description2-Methylhippuric acid is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases, the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) Which is an enzyme that catalyzes the chemical reaction: Acyl-CoA + glycine <--> CoA + N-acylglycine. 2-Methylhippuric acid is a metabolite of xylene which is an aromatic hydrocarbon widely used as a solvant. Its level can be measured in the urine of workers exposed to xylene (PMID:8689499 ). 2-Methylhippuric acid is an endogenous phenolic acid metabolite detected after the consumption of whole grain.
