L-Carnitine and exercises

บทคัดย่อ

Carnitine is a quaternary ammonium compound biosynthesized from the amino acids lysine and methionine in the liver and kidney. L-Carnitine in the body is used for other functions. For example it is well established that in case of Carnitine defi ciency, L-carnitine loading adjusts long chain fatty acid metabolism and their entry into the mitochondria. In addition L-carnitine has a potential effect on exercise capacity and activation of branched amino acid oxidation and stimulation of pyruvate dehydrogenase complex. Athletes consume L-carnitine under the illusion that it would enhance athletic performance and delay fatigue as a result of stimulation of fat oxidation and glycogen storage.
