A decapeptide undergoes partial hydrolysis to give peptides whose amino acid compositions are shown. Reaction of the intact decapeptide with Edmans reagent releases PTH-Gly. What is the sequence of the decapeptide? 1. Ala, Trp 2. Val, Pro, Asp 3. Pro, Val 4. Ala, Glu 5. Trp. Ala, Arg 6. Arg. Gly 7. Glu, Ala, Leu 8. Met, Pro. Leu, Glu Spell out the name of the polypeptide using three letter codes for each amino acid separated with hyphens (for example, Tyr-Lys-Trp).
