Medchemexpress LLC L-Carnitine | 541-15-1 | 99.9% | 1 ML
L-Carnitine, also known as (R)-Carnitine or Levocarnitine, is a highly polar, small zwitterion. It serves as an essential co-factor for the mitochondrial β-oxidation pathway, facilitating the transport of long-chain fatty acyl-CoAs into the mitochondria for degradation. Beyond its role in metabolism, L-Carnitine acts as an antioxidant and can help alleviate metabolic imbalances associated with various inborn errors of metabolism. For optimal stability, store the product at -80°C for up to 1 year or at -20°C for up to 6 months.
- Essential co-factor for mitochondrial β-oxidation pathway
- Transports long-chain fatty acyl-CoAs into mitochondria
- Functions as an antioxidant
- Alleviates metabolic imbalances in various inborn errors of metabolism
