L-carnitine is a vitamin-like substance vit.Bt and in all tissues, with highest concentrations in skeletal muscle and myocardium. They are most dependent on it. As a natural constituent of cells, it plays a major role in the production and transport of energy. The skeletal muscles prefer to use various sources of energy, the myocardium receives about two thirds of its energy from oxidation of fatty acids. L-carnitine is the only independent factor for the penetration of long (more than 12 carbon atoms) fatty acids across the inner membrane mitihondrialna through so-called. “Carnitine shuttle” for beta-oxidation.
