(a)
Interpretation: The structure of peptide Ile-Ala-Gly is to be drawn. The peptide bonds and terminal amino and carboxyl groups are to be labeled.
Concept introduction: Peptides are long chain molecules which are formed by making peptide bond between amino acids. The peptide bond is formed by amino and carboxylic group.
(a)
Answer to Problem 9A
The structure of peptide Ile-Ala-Gly along with the labeled peptide bond and terminal groups is,
Explanation of Solution
Peptide bond is formed when two compounds having
(b)
Interpretation: The structure of peptide Gln-Ser is to be drawn. The peptide bonds and terminal amino and carboxyl groups are to be labeled.
Concept introduction: Peptides are long chain molecules which are formed by making peptide bond between amino acids. The peptide bond is formed by amino and carboxylic group.
(b)
Answer to Problem 9A
The structure of peptide Gln-Ser along with the labeled peptide bond and terminal groups is,
Explanation of Solution
Peptide bond is formed when two compounds having amine group and carboxylic group form bond with each other. One peptide bond is formed when two amino acids form bond with each other. The amino group and carboxylic group which do not participate in bond formation and present at terminal carbon atom are labeled as terminal groups. The structure of peptide Gln-Ser along with the labeled peptide bond and terminal groups is,
(c)
Interpretation: The structure of peptide Ser-Gln is to be drawn. The peptide bonds and terminal amino and carboxyl groups are to be labeled.
Concept introduction: Peptides are long chain molecules which are formed by making peptide bond between amino acids. The peptide bond is formed by amino and carboxylic group.

- Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!!
