Sickle cell anemia is a disease that result from a genetic mutation in the beta globin chain of hemoglobin. This mutation causes a conformational change in the protein structure by substituting a valine for a glutamic acid, the hemoglobin clumps to resist water exposure, and the cell to sickles. Which of the follow is most likely to be true regarding valine vs glutamic acid? (QID 240083)
A. glutamic acid is hydrophobic and causes the hemoglobin to interact with water
B. valine is hydrophobic and causes the hemoglobin to shun the water
C. glutamic acid is hydrophilic and causes the hemoglobin to avoid water
D. valine is hydrophilic and causes hemoglobin to interact with water
