Do alpha and beta chains of haemoglobin carry the same amount of oxygen per chain ?

Dear student

The haemoglobin molecule is a tetramer consisting of 4 polypeptide chains, known as globins, which are usually:

2 alpha chains that are each 141 amino acids long

2 beta chains that are each 146 amino acids long

Attached to each chain is an iron-containing molecule known as haem.
They carry same amount of haemoglobin.
