Web27 jan. 2024 · In summary: Structurally, foetal haemoglobin (HbF) is made up of two α-subunits and two γ-subunits (instead of two β-subunits) This decreases the affinity of HbF for 2,3-DPG. As 2,3-DPG normally decreases the affinity of hameoglobin for oxygen, in the absence of 2,3-DPG binding the oxyhaemoglobin dissociation curve of HbF is left-shifted. fifa 22 ps5 cdkeys
