WebSickle hemoglobin (HbS) is caused by a mutation in the β globin gene which affects the stability and solubility of the β chain. When HbS is deoxygenated (e.g. during inflammation, infection, dehydration or hypoxia) it polymerizes and distorts the red cell, eventually resulting in the characteristic sickle shape. WebHemoglobin Structure. Image by Becky T. S20. Hemoglobin is composed of 8 subunits: 4 polypeptide chains known as globins (2a and 2b) and 4 iron-containing heme-groups. Each heme group contains a single iron atom, which lends erythrocytes their distinctive red crimson color. Each heme group can transport one molecule of oxygen.
