What is Each hemoglobin molecule contains how many globin? and explain in detail?
Ans. is 'a' i.e., 1 Hemoglobin is the most impoant red cell constituent. The hemoglobin molecule is an assembly of four globular protein. Each subunit is composed of a protein (polypeptide) pa, i.e., globin and a nonprotein pa i.e., heme, i.e., Each hemoglobin molecule contains four heme units and two pairs of similar protein, globin. The heme pa of globular protein is same in all types of hemoglobin. The protein pa vary in different hemoglobin : ? Adult hemoglobin (Hemoglobin A) consist of two identical a-chains and two identical n-chains. Fetal hemoglobin (H bF) consists of two identical a-chains and two identical y chains. Minor hemoglobin (HbA2) consist of two identical a-chains and two identical 8 chains. Each hemoglobin molecule consists of globin (4 polypeptide chains) and 4 heme molecules.
