For 10 points, name this interaction between an acid group of one molecule and an N-group of another, a type of bond that links amino acids.
A reagent often employed to destroy them is cyanogen bromide, but a more selective elimination of them can be achieved by the Edman Degradation, which uses PITC to destroy only the terminal one. They are planar because of the resonance interaction between a lone pair of electrons and a carbonyl group, which produces a certain rigidity during folding processes. They usually exist in a trans configuration, with an important exception to this rule being proline.
