Peptide bonds

peptide bond

The amide linkage between the carboxyl group of one amino acid and the amino group of another. The linkage does not allow free rotation and can occur in cis or trans configuration, the latter the most common in natural peptides, except for links to the amino group of proline, which are always cis.
