And so if they point away, there will be no steric hindrance, there will be no bumping of electrons or bumping of atoms, and there will be no electrostatic repulsion as a result of the bumping of atoms in this particular case. But if we flip it to basically form the CIS isomer, the CIS configuration, notice that now this alpha carbon and this alpha carbon, they point along the same direction. And now there will be stair kindle, there will be the bumping of electrons and atoms and that will increase the electrostatic repulsion due to the charges of these atoms. And that will drive the energy of the CIS configuration to be higher than that of the trans configuration. And so in the majority of cases, we only really see the trans peptide bonds and never the cyst configuration bonds because of this idea that this creates a more stable system that is lower in energy. Now, I say in the majority of cases because actually in some cases we do see the CIS configuration, but we'll discuss that in much more detail in future electros.
