Product Introduction
L-Alanine is a non-essential α-amino acid endogenously synthesized and metabolized in mammalian systems. It acts as a key nitrogen shuttle between peripheral tissues and the liver via the glucose-alanine cycle: skeletal muscle releases alanine to the bloodstream; the liver takes up alanine, converts it to pyruvate for gluconeogenesis, and excretes the amino group as urea. This cycle stabilizes blood glucose, sustains muscle energy output, and mediates systemic nitrogen balance. L-Alanine serves as a monomer for polypeptide and enzyme assembly, supports intracellular osmoregulation, and contributes to the natural moisturizing factors (NMF) of epithelial tissues. It is chemically stable under ambient conditions and compatible with standard food, supplement, and cosmetic formulation processes.
