Carnitine is a quaternary ammonium compound involved in the metabolism of most mammals, plants and some bacteria. [1][2][3][4] To support energy metabolism, carnitine transports long-chain fatty acids into the mitochondria for oxidation to generate free energy and participates in the removal of met

Free-floating fatty acids released from adipose tissue into the blood bind to a carrier protein molecule called serum albumin, which transports the fatty acids into the cytoplasm of target cells such as heart, skeletal muscle, and other tissue cells, where they for fuel. But before fatty acids can b
