And not only that, but because we have the double bond character, there will be six atoms arranged along the following diagram as we'll see in just a moment that will lie along the same plane. So the double bond nature of the peptide bond makes the peptide bond planar and prevents any rotation about the peptide bond. So basically this atom number one, this atom number two, this atom number three, this atom number four, this atom number five and this atom number six will all lie along the same plane. So if we place this molecule, let's say on the board and the board is our plane, then all these molecules will lie along the plane of that board. Now let's take a look at the following diagram. Something that we really haven't explained yet is the fact that we see predominantly the trans isomer configuration and not the CIS configuration.
