Another function of L-Carnitine is the transportation of long-chain fatty acids into mitochondria. Here, these fatty acids are oxidized to produce energy. That is, the process of fat burning occurs with the help of L-Carnitine. 

Further, it helps transport the toxic compounds produced in the cells out and prevent their accumulation. As L-Carnitine has to play these key roles, it is found in the cardiac and skeletal tissues.
