WebMar 11, 2010 · The secondary amide peptide bonds that comprise up to one-third of the bonds of peptide or protein backbones can exist as cis and trans isomers, with the trans isomer being highly favored. However, there is little quantitative data on the kinetics and equilibria of cis-trans isomerization of secondary amide peptide bonds due to the … WebCis and Trans Isomerism of Cycloalkanes. The origin of the cis and trans isomerism is the “locked” feature of the double. It locked because there is no rotation around the double bond and this, in turn, means that we cannot switch the orientation of the groups on the double bond. Recall that there is a free rotation about sigma bonds and ...
