The C-terminal alpha-helix is shown in Wireframe, or "Sticks," with H-bonds on. 3.1. There are 16 residues. Examine the H-bonds carefully. How many H-bonds are shown? 3.2. List 4 residues that have 2 H-bonds each. What are the patterns? Are they all i(C=O) to i+4(NH) ? 3.3. List the four residues at the N terminus that make only 1 H-bond. 3.4. How many residues at the C terminus make only 1 H-bond? Next: H-bonding in an beta-sheet
