Question
Chapter 7, Problem 9P
Interpretation Introduction
Interpretation:
The given hemoglobin mutation are:
- β146(HC3) His → Asp
- β 92(F8) His → Leu
To compare native and mutant hemoglobin that would move faster to the anode. pI of hemoglobin is 7.0 and the electrophoresis is done at pH is 8.0.
Concept Introduction:
pI is also known as the isoeletcric point. It is the pH at which an amino has no net charge. The amino acid exists as a zwitterion at its pI. In a zwitterion the net positive charge is balanced by the net negative charge.

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.)
