Hemoglobin and sickle cell anemia
WebSickle cell disease is caused by an abnormal type of hemoglobin called hemoglobin S. Hemoglobin is a protein inside red blood cells that carries oxygen. Hemoglobin S changes the red blood cells. The red blood cells become fragile and shaped like crescents or sickles. The abnormal cells deliver less oxygen to the body's tissues.
