Be sure to answer all parts. An octapeptide contains the following amino acids: Ala, Pro, Gly, Asp, Trp, Lys, Leu, Met. Carboxypeptidase treatment of the octapeptide forms Asp and a heptapeptide. Treatment of the octapeptide with Chymotrypsin forms forms two tetrapeptides, A and B. Treatment of A with Trypsin yields two dipeptides, C and D. Edman degradation cleaves the following amino acids from each peptide: Gly (octapeptide),Gly (A),Met (B), Gly (C), Leu(D).Partial hydrolysis of tetrapeptide B forms Met-Pro in addition...
