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.
