L-Carnitine

L-Carnitine (Levocarnitine) is a naturally occurring quaternary ammonium compound involved in mitochondrial energy metabolism. In research settings, L-Carnitine plays a central role in the transport of long-chain fatty acids into the mitochondria, where they can be oxidized for ATP production. This mechanism makes it a valuable compound for studies investigating cellular energy balance, fatty-acid utilization, and metabolic function.
