    In verteВ­brates, the function of hemoglobin is to transport oxyВ­gen in the blood from the lungs to the tissues, and therefore hemoglobin molecules can exist in two states: oxygenated and un-oxygenated. In all but the lowest vertebrates, hemoglobin is a tetramer. In lampВ­reys, however, hemoglobin is monomeric, that is, it contains a single globin chain. In this regard, lamprey hemoglobin is Hemoglobin present on red blood cells is the vital protein responsible for transport of oxygen and carbon dioxide to and from the body tissues. The current article gives a brief account of the structure and function of this respiratory protein.

    structure and function of hemoglobin pdf

    The Hemoglobin System. VI. The Oxygen Dissociation Curve of Hemoglobin (Adair, G. S. (1925)J. Biol. Chem. 63, 529–545) Gilbert Smithson Adair (1896–1979) was a pioneer in the application of physical chemistry to the study of proteins. Both hemoglobin and myoglobin are composed of closely related globin proteins (see Lehninger p. 210-211 and Fig. 7.7) and heme pigment (Lehninger p.205), which gives blood its characteristic red colour.
