👉 Carnitine is a type of amino acid that plays an important role in energy metabolism. It is found in the liver and muscles, where it is converted into fatty acids and used for energy production. In humans, carnitine is synthesized from acetyl-CoA by the enzyme carnitine palmitoyltransferase II (CPT-II). This process occurs in the mitochondria of the liver and other muscle cells. The resulting carboxyl group is then incorporated into an amino
