Give the first step of the reaction between the following pentapeptide and the reagent Use curly arrows to show how the bond between the reagent and the relevant amino acid residue is formed; there is no need to show the cleavage of the amino acid from the peptide. 7. supplied. ala.phe.asp.met.gly -N-CS with 8. Starting from the "Merrifield resin" shown below, suggest the next step, which would enable you to synthesize a pentapeptide with gly as the N-terminal amino acid. There is no need to show all the steps leading to the synthesis of the pentapeptide; all you are asked is to supply one step with the appropriate reagents. Make sure you write a full structure for the precursor you suggest. val ginry phe Give the first step of the reaction between the following pentapeptide and the reagent Use curly arrows to show how the bond between the reagent and the relevant amino acid residue is formed; there is no need to show the cleavage of the amino acid from the peptide. 7. supplied. ala.phe.asp.met.gly -N-CS with 8.
