Used in biochemical research as a model dipeptide for studying peptide metabolism and enzymatic hydrolysis. Serves as a building block in the synthesis of larger peptides with potential biological activity. Employed in cell culture media formulations to support cell growth by providing a source of amino acids. Also utilized in studies related to taste chemistry, as some dipeptides exhibit sweet or bitter flavors. Its D-glutamine component makes it useful in investigating the effects of D-amino acids in physiological systems.
