Carnitine, also known as <small>L</small>-carnitine (levocarnitine) is a quaternary ammonium compound synthesized from the amino acids lysine and methionine primarily in the liver and kidneys [1]. It helps in the consumption and disposal of fat in the body because it is responsible for the transport of fatty acids from the cytosol into the mitochondria. It is often sold as a nutritional supplement. Originally found as a growth factor for mealworms and labeled vitamin Bt.
