And at the end, we basically know exactly what that sequence of amino acid is in our polypeptide chain. So this process is a very, very useful process because it gives us a systematic approach to cleaving a specific peptide bond and thereby determining exactly what that sequence is. Now, the edgeman degradation process is only useful up to a certain size of that protein. For instance, if our number of amino acids is, let's say, 1000, this is not a very useful process. And we'll see exactly why in the next lecture. In the next lecture, we're going to see how we can basically determine the sequence of amino acids of larger proteins.
