2,3-Diphosphoglycerate: its role in health and disease

2,3-Diphosphoglycerate (2,3-DPG) was first discovered and isolated in 1925. However, it was not until 1967 that the function of 2,3-DPG was explained. This resulted in multiple research projects devoted to elucidating the mechanism by which 2,3-DPG exerts it effect on the oxygen affinity of hemoglobin. In addition, a vast amount of research has been devoted to assessing the role of 2,3-DPG in oxygen transport in various physiological and pathophysiological states. In many instances, the results of this research have produced conflicting data which have dampened the initial enthusiasm which followed the discovery of the function of 2,3-DPG. However, much of this conflicting data can be explained by the fact that 2,3-DPG is only one of a number of factors influencing the transport of oxygen to the tissues. Several of these factors influence oxygen transport independently as well as by altering the synthesis of 2,3-DPG and modifying its effect on hemoglobin. In spite of the conflicting results, the overall data gathered thus far appears to be sound enough to warrant the extensive research now being done, particularly in the area of blood storage and transfusion therapy.
