So the admin degradation process is very useful because it gives us a systematic approach to basically cleaving that first peptide bond and no other peptide bonds are cleaved within that polypeptide chain. Now the admin degradation process is even more useful. How? Well, let's take a look at the following two molecules. So once we isolate this molecule and remove it, we have this peptide bond left. Now, we don't know what the sequence is of these other amino acids.
