These structures are from different forms of hemoglobin. You can use these to compare hemoglobin with and without oxygen and the hemoglobin structures found in two types of sickle cell anemia (Hemoglobin S, and Hemoglobin C).
See how you can use these structures, along with the mRNA, and protein sequences to learn more about hemoglobin and the sickle cell mutation.
