Abstract: The alpha-amino and alpha-carboxyl group in glutamic acid (Glu) were protected by specific coprotection method,γ-Glu-Ser-Gly was synthesized by the liquid peptide method. The prepared mimic tripeptides were used for the chemical mutation of PMSF and H2Se, as well as γ-Glu-SeCys-Gly, The structures of mimic tripeptides were determined by elemental analysis and amino acid analysis. The valency and quantity of Se in mimic tripeptides were determined.

Key words: mimic tripeptide, GPX, synthesis, characterization
