- 6. b. Draw a box around the disulfide bridge in oxytocin, if present, or write "none". 7. Mark each peptide bond in oxytocin by making the corresponding line in the structure thicker or marking it with a different color. The first one is shown for you as an example (in dark orange). 8. Number the central carbon of each amino acid in oxytocin by pointing a small arrow to it or by circling the corresponding vertex in the image. Numbers 1 and 2 indicate the central carbons of the first and second amino acids of oxytocin, and are shown for you as an example. 9. Fill out the following table, listing amino acids that make up oxytocin in order, from the N terminus to the C terminus, characterizing each amino acid by the properties of its R group (side chains), and briefly indicating the reasoning for the characterization.
