Question

How many alpha helix anf beta sheets are there in hemoglobin?

Answer 1

Protein Structure. The hemoglobin molecule 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.

Answer 2

Answer:

Hemoglobin consists of 2 alpha subunits and 2 beta subunits to give a four chain structure.
