Common Name4-Aminohippuric acid
Description4-Aminohippuric 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 Which is an enzyme that catalyzes the chemical reaction:. Acyl-CoA + glycine < -- > CoA + N-acylglycine. Renal proximal tubules secrete various organic anions, including drugs and p-aminohippurate (PAH). Uptake of PAH from blood into tubule cells occurs by exchange with intracellular alpha-ketoglutarate and is mediated by the organic anion transporter 1. PAH exit into tubule lumen is species specific and may involve ATP-independent and -dependent transporters. (PMID 11443229 ). Enhanced secretion of p-aminohippuric acid occurs in Fanconi's syndrome (FS). FS is associated with numerous varieties of inherited and acquired conditions; FS is characterized by a generalized transport defect in the proximal tubules, leading to renal losses of glucose, phosphate, calcium, uric acid, amino acids, bicarbonates, and other organic compounds. (PMID 12552490 ).
