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

L-carnitine is a naturally occurring substance found in food, such as L-carnitine, which occurs naturally in red meat and is synthesized as an over-the-counter nutritional supplement.

L-carnitine has certain functions in some physiological processes of maintaining infant life and promoting infant development. Adults can synthesize and maintain the concentration of L-carnitine required for normal metabolism by themselves, but infants' synthesis ability of L-carnitine is weak, only 12-15% of adults, especially premature infants, which can not meet their normal metabolic needs. Infants grow and develop rapidly, and the required carnitine increases sharply.
