Hemoglobin's main function

Web15 mei 2012 · Of an adult's haemoglobin, 2.2–3.5% is HbA 2, composed of two α- and two δ-chains. This form of haemoglobin is poor at oxygen carriage. Fetal haemoglobin (HbF) comprises two α-chains and two γ-chains. At birth, 50–95% of a baby's haemoglobin is HbF, but these levels decline after 6 months as more HbA is produced. WebOxygen transport, the major function of hemoglobin, is dependent upon reduced heme iron. In the red cell, the heme iron is maintained in the reduced form by the methemoglobin reduction system. When the balance between oxidation and reduction of heme iron is perturbed due to the presence of excessive …
