Likewise, if we take a look at the nitrogen and compare it to this nitrogen, in this particular case, we have three H atoms. In this particular case, we only have one. So when we basically combine A and B to form C, we basically lose two H atoms and one oxygen, and that is a water molecule. So in the process of forming this peptide bond, we always release a water molecule. And that's why this reaction is known as a dehydrolysis reaction or a condensation, because we release a water molecule. So we have amino acid A and B react to form a dipeptide C, and we also release a water molecule.
