Carnitine Palmitoyltransferase (CPT) is an enzyme that plays a crucial role in the metabolism of fatty acids. It facilitates the transport of long-chain fatty acids into the mitochondria, the energy-producing structures in cells. This process is essential for converting fats into energy, particularly during periods of fasting or intense exercise. There are two main forms of CPT: CPT1, located in the outer mitochondrial membrane, and CPT2, found in the inner membrane. Each form has a specific function in the fatty acid oxidation pathway, ensuring that fatty acids are efficiently utilized for energy production in the body.
