Leucine is one of the twenty basic amino acids, which is iso-leucine and isomers of each other. On nutrition, leucine is essential amino acids the human body.

Leucine is the most frequently occurring amino acid in the protein, but also very important for the normal development of the nitrogen balance in infants and childhood and adult body. Presumably, leucine and biochemical methods may be decomposed to maintain protein balance accounts for a very important role on the muscle.

The main food source leucine are: whole grains, milk, dairy products, eggs, pork, beef, chicken, beans, leafy vegetables. Amino acids the human body can not manufacture an additional intake from the diet, as an essential amino acid in weight loss during caloric restriction, leucine and insulin together can help stimulate muscle protein synthesis, thereby preserves (lean body ) muscle tissue, and promote fat burning. Many articles in scientific research pointed leucine-rich diet, can increase the body (lean body) muscle tissue, maintain or increase metabolism, and help to maintain a constant blood sugar. University of Illinois professor of nutrition Don Snow. Rayment (Layman) during the study also found that nearly 15 years, and in the long calorie restriction diet rich in leucine, if provided, to change the weight, body composition (reduction in body fat and increase lean body tissue)

1 promotes protein synthesis, increases (lean) muscle formation, increase metabolic rate. 2 inhibit protein degradation, helping to retain (lean body mass) of muscle tissue, maintain metabolic rate. 3 increase satiety. 4 to maintain constant blood sugar. 5 lower triglycerides. 6 help energy metabolism. 7 hormones and neurotransmitters raw materials. 8 can promote the repair of bone, skin, muscle tissue.
