Metabolite Identification
Common NameL-Octanoylcarnitine
DescriptionL-Octanoylcarnitine is the physiologically active form of octanoylcarnitine (PMID 11274033 ). Octanoylcarnitine is detected in medium-chain acyl-CoA dehydrogenase (MCAD) deficiency. MCAD is characterized by intolerance to prolonged fasting, recurrent episodes of hypoglycemic coma with medium-chain dicarboxylic aciduria, impaired ketogenesis, and low plasma and tissue carnitine levels (OMIM 201450 ). L-Octanoylcarnitine is also found to be associated with celiac disease and glutaric aciduria II, which are inborn errors of metabolism.

Enzymes

General function:
Involved in acyltransferase activity
Specific function:
Beta-oxidation of fatty acids. The highest activity concerns the C6 to C10 chain length substrate. Converts the end product of pristanic acid beta oxidation, 4,8-dimethylnonanoyl-CoA, to its corresponding carnitine ester.
