Product Description:

L-Alanyl-L-glutamine is a dipeptide composed of the amino acids alanine and glutamine. It is a white to off-white crystalline powder that is highly soluble in water. This compound is a stable and soluble source of glutamine, which is a conditionally essential amino acid. Its primary and most significant application is in clinical nutrition, particularly in parenteral (intravenous) nutrition formulations. Glutamine is crucial for immune function and intestinal health, but it is unstable in aqueous solutions. L-Alanyl-L-glutamine serves as a stable dipeptide precursor that is rapidly hydrolyzed in the bloodstream to release free L-glutamine and L-alanine, effectively delivering bioavailable glutamine to patients. Due to its excellent solubility and stability, it is also used as a component in cell culture media and as a buffering agent in certain pharmaceutical preparations.
