Now previously we discussed how these peptide bonds, these green bonds are actually formed. Now let's discuss what the nature of these peptide bonds is. So in other words, are these peptide bonds single bonds as shown in the following diagram or are they something else? Well actually one thing that is not shown in a diagram is the fact that these peptide bonds actually are resonance stabilized. So what exactly do we mean by that? Well, let's suppose we look at the following diagram and what this diagram basically describes is, well let's suppose that we take the following polypeptide.
