General description

L-Leucine is a branched-chain essential amino acid (BCAA). It is one of the nine essential amino acids that must be supplemented in culture systems, as it cannot be synthesized de novo by animal cells. L-Leucine plays a critical role in protein biosynthesis, metabolic regulation, and cellular signaling pathways. In biological systems, L-Leucine is primarily involved in initiating the translation process and promoting ribosomal protein synthesis, particularly through activation of the mTOR (mechanistic target of rapamycin) pathway—a key regulator of cell growth, proliferation, and metabolism. It also serves as a substrate for energy production under nutrient-limiting conditions and contributes to the synthesis of other important biomolecules, such as sterols and fatty acids.
