And so we can see mathematically that's exactly why we cannot use the eggman degradation process on very long polypeptides. So what we conclude is even though the admin degradation process is a very useful process when our amino acids are very short, it becomes pretty inaccurate pretty quickly when our amino acid, when our amino acid number increases in that polypeptide. So how do we solve this problem? Well, the way that we solve the problem is if we have a long polypeptide, we divide that polypeptide, we cut up that polypeptide into very small fragments by using special types of molecules and biological enzymes. And so once we cut up the polypeptide into these fragments, we can then isolate and separate those fragments by using some type of purification technique, for example gel electrophoresis. And then we can use the Edmund degradation process on those individual small fragments.
