WebSuch binding of 2,3-BPG favors the T-state (tight - low oxygen binding) of hemoglobin, which has a reduced affinity for oxygen. In the absence of 2,3-BPG, hemoglobin can more easily exist in the R-state (relaxed - higher oxygen binding), which has a high affinity for oxygen.

Web2,3-Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), promotes hemoglobin transition from a high-oxygen-affinity state to a low-oxygen-affinity state. The 2,3-BPG binds to the central compartment of the hemoglobin tetramer, changing its conformation and shifting the oxygen dissociation curve to the right. WebAn animation of hemoglobin transitioning from the T-state, prevalent in the absence of oxygen, to the R-state, prevalent in the presence of oxygen.
