The protein gamma globulin has an isoelectric point of 6.60. Suppose you did a pH titration of a solution containing gamma globulin. At what pH will the protein aggregate?

 

The protein hemoglobin has an isoelectric point of pI = 7.10. This is the pH at which the number of positive charges on the protein surface equals the number of negative charges on the protein surface.
At which of the following solution pH values will hemoglobin be in solution and at which will it tend to aggregate?
Clear All
pH = 3.35
The protein will be in
solution.
pH = 10.55
The protein will tend to
aggregate.
pH = 7.00
