Leucine, the chemical name is L-2-ammonia-4-methylpentanoic acid, white crystal or crystalline powder; odorless, slightly bitter taste. The slightly soluble density in water is 1.038g/cm3, the melting point is greater than 300ºC, and the boiling point is 217.7ºC at 760 mmHg.
Leucine can be used as a nutritional supplement and flavor enhancer. Amino acid infusions and comprehensive amino acid preparations, hypoglycemic agents, and plant growth promoters can be prepared. Leucine's actions include working with isoleucine and valine to repair muscle, control blood sugar, and provide energy to body tissues. It also helps burn visceral fat, which, because it's located inside the body, can't be effectively affected by diet and exercise alone. Leucine, isoleucine, and valine are branched-chain amino acids that help promote muscle recovery after training. Among them, leucine is the most effective branched-chain amino acid, which can effectively prevent muscle loss because it can be decomposed and converted into glucose faster. Increased glucose prevents damage to muscle tissue, so it's especially good for bodybuilders. Leucine also promotes the healing of bone, skin, and damaged muscle tissue, and doctors often recommend leucine supplements for patients after surgery. Since it is easily converted to glucose, leucine helps regulate blood sugar levels. People with leucine deficiency can experience hypoglycemia-like symptoms such as headaches, dizziness, fatigue, depression, confusion, and irritability.
