The dependence of redox effects of glucose on its concentration (hypothetic relationship suggested by the authors). Hypothetical simplified model describing the influence of the blood concentration of glucose on redox potential in human organisms. Multiple additional factors influencing redox potential such as concentration of oxygen, availability of amino and fatty acids, type of cells and effects of either hormones (insulin, glucagon) or cytokines are not considered. Concentrations of glucose as well as the shape of the curve are roughly estimated and not confirmed by actual experiments and may significantly vary depending on conditions and tissue type.
