Characteristics and properties of carnitine

Characteristics and functions of amino acid carnitine

What is carnitine?

Carnitine is a dipeptide commonly famous for the fat-burning properties attributed to it.

It is a non-essential component, which can be formed from two amino acids: methionine and lysine, plus the presence of vitamin C, vitamin B3 (niacin), vitamin B6 (pyridoxine) and iron. The liver, the kidneys and the brain are the organs in charge of synthesizing it.

Its structure is similar to that of vitamins, it is soluble in water, and its function is to facilitate the transport of essential fatty acids. Carnitine causes fats to reach the cells faster, and then be “burned”.

Carnitine, in addition to contributing to the metabolism of fats, accelerates the metabolism of muscle cells, improving their performance. 90% of the carnitine reserves of the body are found in muscle tissue. For this reason, it is widely used as a sports supplement, both to define muscles, and to accelerate fat burning and sports performance.

Carnitine allows the burning of fatty acids as an energy source, saving muscle glycogen and increasing resistance.
