WebHemoglobin Inside each RBC are millions of molecules of Hb. Four globin protein chains and four iron-binding protoporphyrin (heme) molecules make up each Hb molecule. The … 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.
