L-Leucine

Description:

L-Leucine is an essential branched-chain amino acid (BCAA) that plays a crucial role in protein synthesis and metabolic regulation. It is classified as a hydrophobic amino acid due to its aliphatic side chain, which contributes to its role in protein structure and function. L-Leucine is vital for muscle repair and growth, making it particularly important for athletes and individuals engaged in resistance training. It is also involved in the regulation of blood sugar levels and the production of hormones such as insulin. The chemical formula of L-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. L-Leucine is typically found in high-protein foods such as meat, dairy, and legumes. As a dietary supplement, it is often used to enhance muscle recovery and reduce exercise-induced muscle soreness. Its CAS number, 61-90-5, is a unique identifier that facilitates the identification and regulation of this compound in various applications.
