title: Analysis of the effect of bezafibrate on the oxygen dissociation curve of human hemoglobin.
abstract: Analysis of the effects of a range of concentrations of the antihyperlipoproteinemia drug, bezafibrate, on the oxygen dissociation curve of dilute hemoglobin solutions indicates a 4:1 binding stoichiometry with a site binding constant of 434 mol-1 for deoxyhemoglobin. Analysis of the combined effects of a range of bezafibrate and 2,3-diphosphoglycerate (DPG) concentrations indicates that 2 of the 4 bezafibrate sites are in the vicinity of the DPG binding site, and competitive with DPG binding, and 2 of the sites are remote from the DPG binding site.
