Question
**Question 3:** Concerning the peptide shown below, identify five structural features. **Diagram Description:** The image contains a structural diagram of a peptide. Key features of this peptide include: 1. **Amino Group:** There is a terminal amino group (\(+H_3N\)) on the left side, attached to the alpha carbon. 2. **Peptide Bonds:** The peptide is composed of several amino acid residues linked together by peptide bonds, which are represented by \(-C(O)N-\) linkages. 3. **Side Chain Groups:** - The first residue has a phenyl group (a benzene ring) as its side chain. - The third residue from the left has the side chain \(-CH(CH_3)_2\), indicating a branched aliphatic group (isopropyl group). 4. **Carboxyl Group:** The peptide terminates on the right with a free carboxylate group (\(-COO^-\)). 5. **Backbone Configuration:** The chain has a regular repeating sequence of \(-N-C-C-\) in the backbone structure. **Tasks:** (i) (ii) (iii) (iv) (v)
