CHAPTER 4 Proteins: Structure, Function, Folding
... • Structure of the protein is partially dictated by the properties of the peptide bond • The peptide bond is a resonance hybrid of two canonical structures • The resonance causes the peptide bonds – be less reactive compared to e.g. esters – be quite rigid and nearly planar – exhibit large dipole mo ...
