Leucine is generally used for bread and bakery products. Preparation of amino acid infusion and amino acid preparations, hypoglycemic agents, plant growth promoters. Used as a spice, improve food flavor. In the pharmaceutical industry, the L-leucine is an indispensable raw material of the clinical selection of compound amino acid intravenous fluids, plays an active role in life to maintain the nutrition of critically ill patients need to rescue patients. Leucine also play an important role in regulating amino acid and protein metabolism. The study found that leucine is the only amino acids that can regulate protein turnover in skeletal and cardiac muscle. Also, studies have shown that leucine can promote skeletal muscle protein synthesis. Leucine metabolites. Keto the dissidents acid one also has a role in regulating protein metabolism.
