Propionylcarnitine is metabolized by carnitine acetyltransferase from propionyl-CoA. Increased propionylcarnitine is regarded as a biomarker of vitamin B12 deficiency[1][2].

ChEBI: O-propanoylcarnitine is an O-acylcarnitine compound having propanoyl as the acyl substituent. It has a role as an analgesic, an antirheumatic drug, a cardiotonic drug, a peripheral nervous system drug and a human metabolite. It is functionally related to a propionic acid.
