Metabolite Identification
Common Name3-Methylglutarylcarnitine
Description3-Methylglutarylcarnitine belongs to the class of organic compounds known as acylcarnitines. These are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond 3-Methylglutarylcarnitine is an extremely weak basic (essentially neutral) compound (based on its pKa). 3-Methylglutarylcarnitine is a diagnostic metabolite of 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency. It is also identified in the urine of patients with Reye-like syndrome (PMID: 3958190 , 10927963 ).
