Boc-Tyr(tBu)-Aib-Glu(OtBu)-Gly-OHyog ib qho kev tiv thaiv tetrapeptide feem ntau siv hauv kev tshawb fawb peptide synthesis. Cov pab pawg Boc (tert-butyloxycarbonyl) thiab tBu (tert-butyl) pab pawg tiv thaiv kom tsis txhob muaj kev cuam tshuam sab nraud thaum lub sij hawm peptide saw sib dhos. Kev suav nrog Aib (α-aminoisobutyric acid) pab txhawb cov qauv helical thiab nce peptide stability. Qhov no peptide sib lawv liag yog kawm rau nws lub peev xwm nyob rau hauv conformational tsom xam, peptide folding, thiab raws li ib tug lub tsev thaiv nyob rau hauv tsim bioactive peptides nrog txhim khu kev ruaj ntseg thiab tshwj xeeb.
