Question

What are HbA2 and HbF?

Answer 1

Haemoglobin:

1. Haemoglobin includes an iron-containing heme ring and four globin chains: two alpha and two non-alpha.
2. The construction of the four globin chains concludes the haemoglobin type.
3. Foetal haemoglobin (HbF) contains two alpha and two gamma chains.
4. Adult haemoglobin A (HbA) conveys two alpha and two beta chains, however, haemoglobin A₂(HbA₂) has two alpha and two delta chains.
