L-Carnitine
Based on 20 publication(s) in Google Scholar
L-Carnitine ((R)-Carnitine), a highly polar, small zwitterion, is an essential co-factor for the mitochondrial β-oxidation pathway. L-Carnitine functions to transport long chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. L-Carnitine is an antioxidant. L-Carnitine can ameliorate metabolic imbalances in many inborn errors of metabolism.
