b) your blood is a solution with water and blood cells. red blood cells contain a protein called hemoglobin. normally, hemoglobin is hydrophilic. however, in a person with sickle cell anemia, the hemoglobin on the red blood cells forms long chains in an effort to avoid water. these chains clump together, which results in the sickle shape of the cells. (sickle cell disease)

if glutamic acid (glu) is a polar, hydrophilic molecule, what would you suspect is different about valine (val)?
