L-carnitine, also known as L- carnitine, translated as carnitine in Chinese, is an amino acid that promotes the conversion of fat into energy. Red meat is the main source of L-carnitine, which means L-carnitine is an amino acid derivative separated from meat, so it is called "meat" alkali.
The role of L-carnitine
1, help fat burning
L-carnitine is an essential coenzyme in the process of fat metabolism, which can promote fatty acids to enter mitochondria for oxidative decomposition.
The metabolic process of fat goes through an obstacle, which is mitochondrial membrane. Mitochondria can burn fat to release energy and be consumed by the body, but long-chain fatty acids can't pass this obstacle smoothly. Therefore, L-carnitine has played the role of a porter! Carry the long-chain fatty acids out of the shield bit by bit and send them to mitochondria for further oxidation!
2. Enhance endurance and improve athletic ability.
L-carnitine can promote fatty acids to pass through the mitochondrial membrane for oxidation and energy supply, so it can promote fat burning in the body to provide energy during exercise.
At the same time, L-carnitine can also promote the oxidation and utilization of branched-chain amino acids, and can change the activity of respiratory enzymes in mitochondria, thus improving the ability of aerobic oxidation function of the body.
3. Promote fatigue recovery
Excessive lactic acid production during exercise will increase the acidity of blood and tissue fluid, reduce the production of ATP and lead to fatigue. L-carnitine supplementation can promote the activity of pyruvate deaminase in cells, thus promoting the oxidation and utilization of glucose, which is conducive to delaying the occurrence of fatigue during exercise.
Simply put, when exercising, the liver sugar function in the body will be consumed first, and when the liver sugar is not enough, the fat will be consumed for energy supply. At this time, if the carnitine in the body is not enough and the consumption of fatty acids cannot keep up, it will lead to anaerobic metabolism of liver sugar or glucose, and accumulation of lactic acid will lead to fatigue.
