Hexanoyl Glycine

Hexanoyl Glycine (CAS No.: 24003-67-6) is an endogenous acylated amino acid metabolite detected in urine that serves as a sensitive biomarker in studies of metabolic and genetic disorders, particularly those involving mitochondrial fatty acid oxidation. Formed via conjugation of hexanoyl-CoA and glycine by mitochondrial glycine N-acyltransferase, it reflects perturbations in intermediary metabolism and is widely utilized in research on ethylmalonic encephalopathy and medium-chain acyl-CoA dehydrogenase deficiency, where elevated urinary levels indicate impaired fatty acid β-oxidation. Beyond inherited metabolic diseases, altered levels of hexanoyl glycine have been associated with pathological states such as cancer and environmental stressors including gamma radiation exposure, supporting its broader application in biomarker discovery and toxicological assessment. Although it does not function as a direct pharmacological modulator with defined molecular targets or classical dose–response parameters, it is extensively employed in metabolomics, disease modeling, and preclinical diagnostics to monitor metabolic flux and mitochondrial function. Experimental use in cell-based assays and animal models typically involves analytical quantification under conditions tailored to specific study designs, enabling its integration into drug discovery workflows focused on metabolic regulation and mitochondrial dysfunction.
