Leucine

Description:

Leucine is an essential branched-chain amino acid (BCAA) that plays a crucial role in protein synthesis and metabolic regulation. It is one of the 20 standard amino acids used by cells to synthesize proteins and is particularly important for muscle repair and growth. Leucine is classified as a hydrophobic amino acid due to its aliphatic side chain, which contributes to its role in protein structure and function. The chemical formula for leucine is C6H13NO2, and it features an amino group (-NH2), a carboxyl group (-COOH), and a side chain that distinguishes it from other amino acids. Leucine is commonly found in high-protein foods such as meat, dairy products, and legumes. It is also available as a dietary supplement, often marketed for its potential benefits in enhancing muscle recovery and promoting anabolic processes. In terms of solubility, leucine is soluble in water and has a relatively high melting point. Its CAS number, 328-39-2, is used for identification in chemical databases and regulatory contexts.

DL-Leucine

CAS: 328-39-2

DL-Leucine is an amino acid that is needed for the formation of proteins. It is also able to inhibit the activity of enzymes by hydrolyzing them. DL-Leucine has been shown to be a potent inhibitor of lysine hydrolases and can be used as an additive in the manufacture of animal feed. DL-Leucine has been shown to be stable in many environments, including those containing chlorine, hydrochloric acid, n-dimethyl formamide, and x-ray crystallography. The enantiomers of DL-leucine have different chemical stability; one form is more stable than the other in acidic environments.
