Figure 12. Shift in glutathione redox status with aging, AMD, and diabetes
Calculated redox potential (Eh) for GSH pool in blood plasma of younger and older controls and patients with AMD or diabetes. Values for Eh were calculated as Eh= Eo + RT/ZF ln ([GSSG]/(2[GSH])) where Eo was taken as 0.24 V , R is the universal gas constant, T is the absolute temperature, Z is the valence, and F is the Faraday constant.
