Applications

Glycylglycylglycine is used as a model peptide for studies of physicochemical parameters and molecular associations of small peptides. Triglycine is used as a copper chelator. It also acts as substrate for reproducible serum protein measurements by the biuret reaction1 and for the assay of aminotripeptidases
