Common NameTiglylglycine
DescriptionTiglylglycine 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. Tiglylglycine is an intermediate product of the catabolism of isoleucine. An elevated level of tiglylglycine is identified in urine of patients with beta-ketothiolase deficiency or with disorders of propionate metabolism (PMID 7923765 ). Tiglyglycine is a biomarker for the consumption of cheese.
