The dynorphins are a group of opioid peptides that play an importantrole in changes in the brain associated with cocaine addiction. One ofthese peptides, dynorphin A, contains the following amino acidsequence: Tyr–Gly–Gly–Phe–Leu–Arg–Arg–Ile–Arg–Pro–Lys–Leu–Lys.Draw the amino acids and peptide fragments formed when dynorphin A is treated with each reagent or enzyme: (a) chymotrypsin; (b) trypsin; (c)carboxypeptidase; (d) C6H5N=C=S.
