Аннотация:
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 the π-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. © 1986 Plenum Publishing Corporation.
