In vitro effects of fructose-1,6-diphosphate on oxygen affinity and electrolyte equilibrium in human blood.
The in vitro effects of a solution of fructose-1,6-diphosphate on hemoglobin-oxygen affinity and electrolyte distribution between plasma and red cells were evaluated. Fructose-1,6-diphosphate increased intracellular pH and decreased extracellular pH. There were no shifts in Na+, K+, Ca++ and Cl- between plasma and red cells. Red cell content of 2,3-diphosphoglycerate remained unchanged, while P50 was reduced (as a consequence of the intracellular alkalosis). The therapeutical implications of these results are discussed.
