Medchemexpress LLC L-Carnitine-d9 chloride | 2687961-04-0 | 99.0% | 1 MG
L-Carnitine-d9 chloride is the deuterium-labeled L-Carnitine chloride. L-Carnitine chloride is a highly polar, small zwitterion that acts as an essential co-factor for the mitochondrial β-oxidation pathway. Its function is to transport long-chain fatty acyl-CoAs into the mitochondria for degradation by β-oxidation. Additionally, L-Carnitine chloride is an antioxidant and can help ameliorate metabolic imbalances in various inborn errors of metabolism.
