Determining The Conformation Stability Of Glycine-α-polypeptide By No-bonded Interaction And The Coulomb Model

1.　The　features　of　the　conformers'structures　were　analyzed,　the　parameters　of　twelve　no-bonded　interactions　have　been　determined.　These　parameters　and　the　structures　of　52　glycine-α-polypeptides　have　been　taken　into　account　the　relative　conformational　energies.　And　the　agreement　with　B3LYP　data　is　very　good.　2.　The　Coulomb　Model,　K 　parameters　have　been　developed　that　nicely　reproduce　the　relative　conformational　energies　of　52　polypeptides　with　the　atomic　charges　which　were　determined　by　using　a　6-31G*　basis　set.　Furthermore,　we　have　determined　the　conformation　stability　of　glycine-α-polypeptide.　As　we　can　see,　The　Coulomb　Model　and　K　parameters　do　a　good　job　of　reproducing　the　relative　conformational　energies.
