Palmitoyl-L-carnitine, also known as L-Palmitoylcarnitine, is a biochemical which may influence the activity of several enzymes and transporters Palmitoyl-L-carnitine is localized in the mitochondrial membrane and facilitates the transfer of long-chain fatty acids from the cytoplasm into the mitochondria during the oxidation of fatty acids. L-Palmitoylcarnitine has been shown to accumulate during ischemic myocardium and potentially contribute to myocardial damage through alterations in membrane molecular dynamics.
