L-Carnitine hydrochloride
Based on 22 publication(s) in Google Scholar
L-Carnitine hydrochloride ((R)-Carnitine hydrochloride), a highly polar, small zwitterion, is an essential co-factor for the mitochondrial β-oxidation pathway. L-Carnitine hydrochloride functions to transport long chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. L-Carnitine hydrochloride is an antioxidant. L-Carnitine hydrochloride can ameliorate metabolic imbalances in many inborn errors of metabolism.
