Textbook Question
Chapter 4, Problem 6P
Using the pKa data in Table 4.1 and the Henderson-Hasselbalch equation, calculate the approximate net charge on each of the four common ribonucleoside 5'-monophosphates (rNMPs) at pH 3.8. If a mixture of these rNMPs was placed in an electrophoresis apparatus, as shown, draw four bands to predict the direction and relative migration rate of each.

12. When glutamic acid is heated to 180°C., it loses a molecule of water to form a
lactam. The bond that creates the lactam is an amide bond that forms between the
amino nitrogen and the carbon of the side chain -COOH group. What is the most
reasonable structure for this lactam? (NOTE: The structure of glutamic acid is shown
in Question 1.)
