Hemoglobin (Haemoglobin in many varieties of English) is a tetramer consisting of two dimers that binds to oxygen. Hemoglobin is the oxygen binding protein of red blood cells and is a globular protein with quaternary structure.Hemoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains. Hemoglobin transports oxygen in the blood from the lungs to the rest of the body.The three-dimensional structure of hemoglobin was solved using X-ray crystallography in 1959 by Max Perutz.emoglobin consists of four polypeptide subunits; 2 alpha chains and two beta chains.

Hemoglobin Structure. Hemoglobin is the molecule that is responsible for the oxygen carrying capacity of a red blood cell. It also gives these cells a red color and is a combination of heme and globin. Heme is formed when succinyl-CoA binds with glycine to form a pyrrole molecule.part from carrying oxygen, which is the main function of red blood cell, it can also conduct the following functions. 1  Release the enzyme carbonic anhydrase which allows water in the blood to carry carbon dioxide to the lungs where it is expelled.
