摘要:To evaluate Flory's isolated-pair hypothesis in the context of helical peptides, we explore equilibrium conformations of -helix-forming polypeptides as a function of temperature by means of replica exchange molecular dynamics in conjunction with the CHARMM/GB implicit solvent force field and the weighted histogram analysis method. From these simulations, Zimm-Bragg parameters, s and {sigma
