So we have these two electrons basically form this pi bond. Here. We get the following diagram. And so these two electrons in this pipeline between the carbon and oxygen basically go on onto the orbital around the oxygen and we form a negative charge on the oxygen, a positive charge on a nitrogen, but at the same time we have a double bond between the carbon and that nitrogen. So we see that although this bond isn't exactly a double bond, it's also not exactly a single bond. It's somewhere in between because these two resonance stabilized structure describes the actual structure of that peptide bond which is somewhere in between.
