Haemoglobin

Haemoglobin

Normal adult haemoglobin molecule (HbA) consisting of α2 β2 globin chains, each with its own haem group in oxy and deoxy state. The haemoglobin tetramer can bind up to four molecules of oxygen in the iron containing sites of the haem molecules. As oxygen is bound, salt bridges are broken, and 2,3-BPG and CO2 are expelled.
