Metabolite Identification
Common NamePalmitoylglycine
DescriptionPalmitoylglycine is an acylglycine with C-16 fatty acid group as the acyl moiety. Acylglycines 1 possess a common amidoacetic acid moiety and are normally minor metabolites of fatty acids. Elevated levels of certain acylglycines appear in the urine and blood of patients with various fatty acid oxidation disorders. They are normally produced through the action of glycine N-acyltransferase which is an enzyme that catalyzes the chemical reaction: acyl-CoA + glycine ↔ CoA + N-acylglycine.
