Chemical structure of carnitine
Quaternary ammonium cation.

Carnitine is a quaternary ammonium compound (or salts of quaternary ammonium cations; those cations are positively charged polyatomic ions of the structure NR+
, where R is an alkyl group or an aryl group).

Carnitine is part of (the process of) metabolism in most mammals, plants, and some bacteria.[1][2][3][4]

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.[3] 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.[3]

Doping in sport[change | change source]

L-Carnitine is not on the doping list of World Anti-Doping Agency, or WADA, but people in sport got punishment in 2019, for [the way that they] used L-Carnitine.[5][6][7] (See doping in sport.)
