Saccharide iron oxide

Oxidative stress and inflammation are elevated in hemodialysis patients, which, at least partly, might be initiated by intravenous iron administration. Thus, Tovbin et al. [377] showed that the administration of iron saccharide to hemodialysis patients increased the blood level of oxidized proteins. Similarly, an increase in the levels of free ( nontransferrin-bound or labile ) iron has been shown in the plasma of hemodialysis patients [378] including patients after intravenous iron saccharate infusion [379]. 

At The American University, Isbell s major interest in research turned to the study of the oxidation of saccharides with hydrogen peroxide. In collaboration with Dr. Frush, he published some forty papers on the subject. A number of major discoveries were made, including that of a stepwise degradative peroxidation, which is catalyzed by base or by such metals as iron(II). It starts at the anomeric carbon of an aldose, either in the acyclic or the cyclic form, and affords the lower aldose and formic acid (see Fig. 8). Two mechanisms were recognized an ionic one prevalent in strong alkali, and a free-radical process catalyzed by Fe(II) (see Fig. 9).
