-
lt has more affinity for oxygen.

But it has only one
Fe2 group , the curve obtained will be hyperbolic , than being sigmoid.

- FETAL HAEMOGLOBIN:
- What is Fetal haemoglobin??????
www.cloudfront. in
- Fetal haemoglobin has higher affinity for
O2 because it binds BPG less strongly ( 2,3 Biphosphoglyceric acid ) . BPG act as negitive regulator , it enhancesCO2 binding and preventsO2 binding. - ADULT HAEMOGLOBIN:
- What is Adult haemoglobin????
www.cloudfront. net
- The most common haemoglobin type is Tetramer. It has 4 subunits:
-2 alpha
-2 beta
These subunits are non covalently bonded.
