(Redirected from Palmitoyl carnitine)
Palmitoylcarnitine is an ester derivative of carnitine (long-chain acylcarnitine) involved in the metabolism of fatty acids. Within the cell, palmitoylcarnitine is transported into the mitochondria to deliver palmitate for fatty acid oxidation and energy production.
Carnitine palmitoyltransferase I (CPT1) also known as carnitine acyltransferase I or CAT1 is a mitochondrial enzyme. CPT1 is associated with the outer mitochondrial membrane and mediates the transport of long-chain fatty acids across the membrane by binding them to carnitine.
