Carnitines

Introduction

Carnitines are widely distributed in nature and their potential health benefits have been popularized. Free carnitine (3-hydroxy-4-N-trymethylaminobutyric acid) was first isolated from bovine muscle by Russian scientists in 1905 and only the L-isomer (L-carnitine, LC) was found bioactive. In 1955, Fritz found that LC could accelerate lipid metabolism and then identified its pivotal role in mitochondrial β-oxidation of long-chain fatty acids for cellular energy production. Moreover, carnitine protects cell membrane and DNA against damage induced by free oxygen radicals. It also prevents protein oxidation and lactate oxidative damage.

In fact, LC could be biosynthesized by human body. However, LC present in human tissues is mainly of exogenous origin from meat, poultry and fish in dietary. It has long been assumed that carnitine is not an essential component of diet as humans have the ability to synthesize this compound. However, when groups of strict vegetarians were studied, the results showed that their average plasma concentration of carnitine was significantly lower than those of the respective omnivorous controls, which may be attributed to the much less carnitine that strict vegetarians consumed per day. In 1973, Engel reported the first case of carnitine deficiency and treated it with carnitine supple-mentation.

L-carnitine is a substance that occurs naturally in the body and that the organism is able to produce in a certain amount. Its synthesis is dependent on the presence of the amino acids L-lysine and L-methionine and vitamins B3, B6, C and iron. L-carnitine improves the transport of fatty acids with a long chain (fat) into the itochondria, where they are "burned" and then used as energy. L-carnitine is suitable in the diet for power sport activity, but also for endurance sports.
