- It is present until about 2 - 4 months after birth.
- It replaces the α sub units with γ sub units.
- It binds 2,3 BPG tightly.
- It has a greater affinity for oxygen than myoglobin.
- Fetal hemoglobin is mostly in the T-state.
Fetal hemoglobin is composed of which of the following?
- Two alpha and two gamma sub units
- Two alpha and two beta sub units

Excellent lecture, well explained so I could understand it. So important to understand and not just memorize these topics.
