Yamamoto® Nutrition Carnitine 1000 is a dietary supplement of Carnitine in 1000 mg tablets, (carnitine tartrate), useful in cases of reduced dietary intake of this nutrient. Carnitine is the vitamin-like compound responsible for the transport of long-chain fatty acids in cellular units of energy production: the mitochondria. Its importance lies in the fundamental role it plays in the transport of fatty acids in the mitochondria. Since the carrier molecule of fatty acids, acyl-CoA, can not cross the cell membrane of the mitochondria, a deficiency of carnitine causes a reduction in the concentration of fatty acids in the mitochondria and, consequently, a reduced production of energy. Fatty acids must be transferred from the CoA to the carnitine. The acyl-carnitine molecule transports the fatty acid to the mitochondrial surface of the inner mitochondrial membrane where it releases it to be transformed into energy (fat is ‘burned’). The camitin performs many other physiological functions, including the conversion of the ketoacid analogs of branched chain amino acids, valine, Ieucine and isoleucine, an extremely important function in fasting, inediation and during exercise.
