Carnitine (carnitine), or transliteration of carnitine, is a class of amino acids, belonging to the cationic quaternary ammonium compound, can be synthesized through biosynthetic generated from the two kinds of amino acids lysine and methionine [1]. Carnitine there are two stereoisomers: comprising biologically active L- carnitine, and its non-biological active enantiomer D- carnitine [2]. Chemically synthesized compounds both L-carnitine and D exist, it is generally in the form of "DL- carnitine" marked.
L- carnitine is a similar vitamin nutrients present in the heart, brain and skeletal muscle inside. Its main task is to transport fatty acids penetrate the cell wall to reach the cells of plants: gland mitochondria to provide energy to the heart and bone cells. Coronary artery disease refers to the delivery of blood to the heart of one or more of the narrowed artery, so the amount of oxygen to the heart will become less. L- Carnitine is especially useful for patients with coronary artery disease, heart because it allows more to make good use of the limited amount of oxygen. Several studies have shown that taking L- carnitine supplements heart patients can move longer and more laborious and not chest pain. It's another cardiac function is to: reduce high cholesterol and good cholesterol while increasing the content of DHL. L- carnitine has recently been marketing to build up their strength, lose weight Sports supplements, and research on the demands made by this point, there are both positive and negative results: Some studies show L- carnitine can greatly enhance aerobic capacity and exercise performance; while some studies deny it. But a lot of hearsay evidence, L- carnitine can enhance physical fitness, and many people swear that it makes them feel energetic and athletic ability are greatly increased. L- carnitine also promotional become the prevention or treatment of certain symptoms of Alzheimer's disease and aging caused. In test tube studies and animal studies being, L- carnitine can show damage caused by free radicals in the brain cells of roughly repair this damage and the situation is common in Alzheimer's patients taking L- carnitine, they mental performance standard assessment tests showed mental deterioration has slowed the trend rate.
