More Basic view


Glycyl-glutamine (Glycyl-L-glutamine), as a enzymatic cleavage product of β-endorphin, is apparently an endogenous antagonist of beta-endorphin(1-31) in several systems. Glycyl-glutamine (Glycyl-L-glutamine) is an activate and stable glutamine-containing neuropeptide over glutamine (Gln).


Glycyl-L-glutamine is used as a thermostable substitute for glutamine in mammalian cell culture medium.
As an amino acid nutritional drug, it can be used to improve the cellular immune function of patients. Effectively reduce the risk of infection in critically ill patients, especially for the treatment and recovery of critically ill patients such as severe infections and malignant tumors.
