| Abstract: | The present paper is devoted to the study of the conformational transition of polypeptides which are capable of forming alpha-helix, beta-structure and random coil conformations with the finite homogeneous chain model. The experimental results on the surfactant-induced conformational change of poly(L-lysine) can be well described by the present model assuming cooperative binding of the surfactant ions to the polypeptide side groups. |
