The properties of individual hemoglobins are consequences of their quaternary as well as of their secondary and tertiary structures. The quaternary structure of hemoglobin confers striking additional properties, absent from monomeric myoglobin, which adapts it to its unique biologic roles. The allosteric (Gk alios other, steros space ) properties of hemoglobin provide, in addition, a model for understanding other allosteric proteins (see Chapter 11). [Pg.42]

Despite all these studies of proteins and synthetic models, many essential aspects of the function of myoglobin and hemoglobin, e.g. the way the protein controls the binding of ligands (02, CO, and NO), the precise structure of the Fe-ligand bonds and the structure-spin-energy relationships at the active center, are a topic of debate [2]. [Pg.78]
