Normal red blood cells are disk - shaped , but in sickle - cell disease , the
abnormal hemoglobin molecules tend to crystallize , deforming some of the cells
into a sickle shape ( Figure 5.21 ) . The life of someone with the disease is

If the denatured protein remains dissolved , it can often renature when the
chemical and physical aspects of its environment are restored to normal . Most
proteins become denatured if they are transferred from an aqueous environment
to an ...
