L-Isoleucine(CAT: R044006) is one of the nine essential amino acids, characterized by its branched-chain aliphatic structure with the molecular formula C₆H₁₃NO₂. It plays a critical role in protein biosynthesis, muscle metabolism, and energy regulation, particularly during exercise and stress. As a branched-chain amino acid (BCAA), L-isoleucine is actively involved in hemoglobin formation, glucose uptake, and tissue repair. It is widely used in cell culture media, nutritional supplements, and biochemical research. Naturally occurring in many dietary proteins, L-isoleucine must be obtained through food or supplementation.
