L-Isoleucine
CAS Number: 73-32-5
L-Isoleucine is a branched-chain essential amino acid required for muscle protein synthesis, energy metabolism, and immune regulation in livestock and poultry. It is often limiting in low-protein diets formulated with crystalline amino acids when the BCAA ratio becomes imbalanced. Our feed-grade L-Isoleucine is manufactured by fermentation and meets strict quality specifications.
