Q: What is the difference between adult and fetal haemoglobin? A:Haemoglobin (Hb), the oxygen carrying protein present in our red blood cells, is made up of an iron containing Haeme molecule surrounded by a protein called Globin.Each Hb molecule contains two pairs of globin chains. Different Hbs are found in humans during the embryonic, fetal and adult life and they differ from each other in. Sep 28, 2007 · Best Answer: Fetal hemoglobin (also hemoglobin F or HbF) is the main oxygen transport protein in the fetus during the last seven months of development in the uterus. Functionally, fetal hemoglobin differs most from adult hemoglobin in that it is able to bind oxygen with greater affinity than the adult form, giving the developing fetus better access to oxygen from the mother's bloodstream.Status: Resolved.

Comparing the molecular structure differences between HbF and HbA that affect BPG binding Fetal hemoglobin (HbF) is the predominant form of hemoglobin expressed in the developing fetus. HbF appears in fetal blood a few weeks post-conception and usually persists at some level in the new born for a few months post-birth.

Dec 24, 2016 · Difference between Fetal & Adult Hemoglobin • Hemoglobin A is composed of two alpha and two beta chains while Hemoglobin F is composed of two alpha and two gamma chains. • Fetal hemoglobin life span is less (about 80 days) as compared to that of HbA (120 days). • Fetal Hb has greater affinity for oxygen as compare to the Adult Hb mainly.
Haemoglobin A is present in major amout almost above 90 person in normal human after birth, while foetal hemoglobin is the only hemoglobin in futus but after birth its amnout is decreased to 2 percent due to the production of Hb A.
