WebCis–trans isomerization [ edit] Peptide bonds to proline, and to other N -substituted amino acids (such as sarcosine ), are able to populate both the cis and trans isomers. WebThe trans form is preferred overwhelmingly in most peptide bonds (roughly 1000:1 ratio in trans:cis populations). However, X-Pro peptide groups tend to have a roughly 30:1 ratio, presumably because the symmetry between the C α and C δ atoms of proline makes the cis and trans isomers nearly equal in energy, see the figure.

WebIn many cases, the cis-trans isomers of a compound have different physical properties. These differences can arise due to the difference in the dipole moment of the molecule or due to the difference in the spatial arrangement of atoms. Some of these differences are highlighted below.
