- Please help me how to solve this question. Thank you very muchAgamemnon just got his first octapeptide to sequence. Identify the correct sequence from the data gathered below. He first did a complete acid hydrolysis and identified the amino acids using HPLC. He found he had a lle, Ala, Ser, Asp, Asn, Phe, His, and an Arg. He submitted the octapeptide to conditions of Edman degradation and got the structure below. H. но He used carboxypeptidase and generated a His and a heptapeptide. He used chymotrypsin and generated a5-amino acid sequence and a 3-amino acid sequence. He used trypsin and generated a 2-amino acid sequence and a 6-amino acid sequence. Partial hydrolysis of the nonapeptide yielded the fragments RIS, NAH, and SF among others.NaOD, D20 What is the product?
