aminoacid active in mitochondria From Wikipedia, the free encyclopedia
Carnitine is an amino acid. It is an ammonium compound used in the metabolism of most mammals, plants, and some bacteria.[1][2][3][4]
When getting 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 important role, carnitine is concentrated in tissues like skeletal muscle and cardiac muscle that metabolize fatty acids as an energy source.[3]
L-Carnitine is not on the doping list of World Anti-Doping Agency, or WADA, but people in sport got punished in 2019, for the way they used L-Carnitine.[5][6][7] (See doping in sport.)
