Conformational analyses of cyclic tetrapeptides consisting of alternating cis and trans peptide units have been made using contact criteria and energy calculations. This study has been restricted to those structures having a symmetry element in the backbone ring, such as a twofold axis ( d ) or a ce
The interaction between cyclic peptides [cyclo-(Sara), cyclo-(Pro-Sar-Gly)r, cyclo-(Sar-Sar), and cyclo-(Sar-Gly)] with benzene has been investigated by nmr spectroscopy. The experiment with cyclo-(Sarr) showed that benzene int,eracted preferentially with the frans peptide bond in a similar manner t
