Overview
L-Carnitine is a quaternary ammonium compound with a chemical structure similar to amino acids, though it is not a component of proteins. Its core physiological function is to serve as a mitochondrial carrier, transporting long-chain fatty acids from the cytoplasm into the mitochondrial matrix for β-oxidation, thereby generating ATP energy.
