Carnitine is a quaternary ammonium compound (or salts of quaternary ammonium cations; those cations are positively charged polyatomic ions of the structure NR+
4, where R is an alkyl group or an aryl group).
During energy metabolism (or during the process of generating energy (ATP) from nutrients), Carnitine transports long-chain fatty acids into mitochondria so that it can be oxidized for energy production; Carnitine also also takes part in removing products of metabolism from cells. Because of its key roles (or important roles), carnitine is concentrated in tissues - or much carnitine can be found in tissues - like skeletal muscle and cardiac muscle that metabolize fatty acids as an energy source.
