3-Hydroxyhippuric 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. 3-Hydroxyhippuric acid is an organic acid found in normal human urine. 3-Hydroxyhippuric acid is a metabolite of rutin detected in urine after consumption of tomato juice (a source of rutin). 3-Hydroxyhippuric acid has its origin in dietary procyanidins (a major source of polyphenols consisting of elementary flavan-3-ol (epi)catechin units). 3-Hydroxyhippuric acid is a microbial aromatic acid metabolite derived from dietary polyphenols and flavonoids, found in normal human urine. It is a marker of gut Clostridium species. Higher levels are associated with higher levels of Clostridia.
