Quaternary ammonium salts
Medchemexpress LLC L-Carnitine | 541-15-1 | MFCD00038747 | 100.0% | 50 G
L-Carnitine, also known as (R)-Carnitine or Levocarnitine, is a highly polar, small zwitterion that serves as an essential co-factor for the mitochondrial β-oxidation pathway. Its primary function involves transporting long-chain fatty acyl-CoAs into the mitochondria for degradation through β-oxidation. L-Carnitine also acts as an antioxidant and has demonstrated the ability to ameliorate metabolic imbalances in various inborn errors of metabolism. This product is intended for research use only.
