WebSummary. Hemoglobin is the oxygen-carrying pigment present in the red blood cells. It is a tetramer having two alpha chains and two beta chains. It is considered to be made up of two dimers, each dimer including one alpha and one beta chain. One heme group is associated with each polypeptide chain. WebHemoglobin is a good example of a protein that has a quaternary structure. Globular proteins are soluble in water and tend to be involved in metabolic functions, as opposed to fibrous proteins which tend to have a structural role.
