WebBoth Hemoglobin A and Hemoglobin S contain four subunits, each made up of eight alpha helices (2). HbA and HbS have significantly similar tertiary structures with a comparative Z score of 28.9 (9). Both hemoglobin proteins have T and R quaternary structural states, but only deoxyhemoglobin S forms fourteen stranded semi-helical polymer chains (8). WebThese proteins are specialised in the binding of oxygen. Myoglobin is made up of 1 individual protein chain responsible for the transport and storage of oxygen in the muscles. Hemoglobin consists of 4 subunits (2 alpha globin chains and 2 beta globin chains) and is present in the blood to transport oxygen around the body.
