What is Alanylglutamine? What exactly is “Alanylglutamine”? It is a dipeptide formed by the chemical bonding of two amino acids: alanine and glutamine. Glutamine is a “conditionally essential amino acid” that has low solubility in water and is unstable. Alanylglutamine, on the other hand, is a stable and more efficient form of glutamine for transport. Jingjing Pharmaceutical’s Alanylglutamine is produced using an enzymatic process, making it safer and more stable.
