What is hemoglobin F? Why does the fetus need a different hemoglobin? |
|
Answer» Haemoglobin F is the haemoglobin found in the mammalian fetus and haemoglobin A is the normal haemoglobin. Haemoglobin F has a higher affinity for oxygen. The fetus needs haemoglobin capable of extracting oxygen from the mother’s circulation. Therefore the fetus uses haemoglobin F since it has a higher affinity for oxygen than the mother’s haemoglobin. |
