Metabolite Identification
Common NameSalicyluric acid
DescriptionSalicyluric acid is an aryl glycine conjugate formed by the body to eliminate excess salicylates, including aspirin. Aspirin is rapidly hydrolysed to salicylic acid which is further metabolized to various compounds, including salicyluric acid (SU) as well as various acyl and phenolic glucuronides, and hydroxylated metabolites. SU is the major metabolite of SA excreted in urine and it is present in the urine of people who have not taken salicylate drugs, although it has no anti-inflammatory effects in humans or in animals. More salicyluric acid (SU) is excreted in the urine of vegetarians than in non-vegetarians, primarily because fruits and vegetables are important sources of dietary salicylates. However, significantly less (10-15X) SU is excreted by vegetarians than individuals taking low-dose aspirin (PMID: 12944546 ). The induction of the salicyluric acid formation is one of the saturable pathways of salicylate elimination. The formation of the methyl ester of salicyluric acid is observed during the quantitation of salicyluric acid and other salicylate metabolites in urine by high-pressure liquid chromatography. This methyl ester formation causes artificially low values for salicyluric acid and high values for salicylic acid. (PMID: 6101164 , 6857178 ). Salicyluric acid has been found to be a microbial metabolite.

Enzymes

General function:
Involved in glycine N-acyltransferase activity
Specific function:
Mitochondrial acyltransferase which transfers an acyl group to the N-terminus of glycine and glutamine, although much less efficiently. Can conjugate numerous substrates to form a variety of N-acylglycines, with a preference for benzoyl-CoA over phenylacetyl-CoA as acyl donors. Thereby detoxify xenobiotics, such as benzoic acid or salicylic acid, and endogenous organic acids, such as isovaleric acid.

Mitochondrial acyltransferase which transfers the acyl group to the N-terminus of glycine. Conjugates numerous substrates, such as arachidonoyl-CoA and saturated medium and long-chain acyl-CoAs ranging from chain-length C8:0-CoA to C18:0-CoA, to form a variety of N-acylglycines. Shows a preference for monounsaturated fatty acid oleoyl-CoA (C18:1-CoA) as an acyl donor. Does not exhibit any activity toward C22:6-CoA and chenodeoxycholoyl-CoA, nor toward serine or alanine.
