Abstract:
Conclusions
1. Quantum-chemical calculations have shown that the coordination of a proton at the oxygen atom is favored by 96 kM/mole relative to coordination at the nitrogen atom.
2. Proton coordination at the formamide oxygen atom leads to a significant increase in theπ-bond order and barrier to internal rotation about the peptide bond.
3. Structural strain in the polypeptide chain may make coordination of an electron-withdrawing agent at the nitrogen atom of a peptide bond energetically favored, which would lead to an increase in the flexibility of the polypeptide chain.
