Question

Alpha chain and beta chain of haemoglobin relate to its function

Answer 1

Protein Structure. The hemoglobinmolecule is made up of four polypeptide chains: two alpha chains < >of 141 amino acid residues each and two beta chains < > of 146 amino acid residues each. The alpha and beta chains have different sequences of amino acids, but fold up to form similar three-dimensional structures.
