摘要：

(Graph Presented) cis persists: The population of the cis conformation of the Cys-Pro imide bond of the cyclic disulfide form of peptides of the sequence Ac-Cys-Pro-(Xaa)m-Cys-NH2 (Xaa = Phe, Ala) ranges from 9.3 to 76.9% and shows a striking periodic dependence on the number of residues in the peptide. © 2006 Wiley-VCH Verlag GmbH & Co.
