(1) Using a highlighter, highlight the entire amino acid backbone, above. That's everything expect the R group and the Hydrogen on the central carbon. Now, a. (1) Draw and label an arrow on the diagram pointing toward the N-terminal end of this polypeptide. b. (1) Put an X through ONE of the peptide bonds. c. (1) Draw a box around ALL of the R-groups. Most people missed 1-2 R-groups, or else missed them all. d. (1) Circle one residue, and only one residue.
