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. WebAbstract. Haptoglobin (Hp) belongs to the family of acute-phase plasma proteins and represents the most important plasma detoxifier of hemoglobin (Hb). The basic Hp molecule is a tetrameric protein built by two α/β dimers. Each Hp α/β dimer is encoded by a single gene and is synthesized as a single polypeptide. biographical synonym

4.2: Oxygen Transport by the Proteins Myoglobin and Hemoglobin

WebFrom what I know, the main function of red blood cells (RBCs) is hemoglobin transport. So, why do we need cells packed with hemoglobin: why can't it travel freely in the bloodstream?
