L-Alanyl-L-Glutamine

L-Alanyl-L-glutamine is a dipeptide consisting of two amino acids, L-alanine and L-glutamine, connected with a peptide bond. Whereas glutamine is unstable when dissolved in water, and is easily broken down by heat, L-alanyl-L-glutamine is more stable (90% remains after 20 minutes at 122℃), and has a higher level of solubility (more than 10 times of L-glutamine, approximately 500g/L at 20℃). Aside from being used as a stable glutamine resource for amino acid transfusion, increased uses in sports nutrition and enteral nutrition are also expected.
