L-Leucine
CAS Number: 61-90-5
L-Leucine is the most abundant branched-chain amino acid in muscle protein and a key activator of the mTOR signalling pathway that drives protein synthesis in livestock and poultry. It is used to fine-tune BCAA ratios in synthetic amino acid diets and supports muscle accretion in fast-growing animals. Our fermentation-derived product delivers consistent purity for precise nutritional formulation.
