Elemental selenium and glutathione reductase
Medical Hypotheses, 1985Selenium is an essential trace element important to several metabolic processes, although selenium in the chemical form of elemental selenium (Se degree) is commonly believed to be biologically inert. Recent data shows that colloidal suspensions of red amorphous elemental selenium are more easily reduced than previously thought, and that such ...

Abstract Glutathione reductase (ECI .6.4.2) catalyses the reduction of GSSG by NADPH, producing 2 mol GSH from 1 mol GSSG. The enzyme contains FAD and redox-active disulfide at the active centre (1). The optimum pH is broad and centred at pH 7.6.

A role for glutathione and glutathione reductase in control of corneal hydration
Experimental Eye Research, 1984We have assessed the importance of the glutathione redox system of the corneal endothelial cells in the control of stromal hydration. The ability of freshly isolated corneas to maintain normal hydration during perfusion, while the activity of glutathione reductase was inhibited with 1.3-bis(2-chloroethyl)-1-nitrosourea (BCNU), was tested under a number

Abstract The total glutathione content of biological samples is conveniently determined with an enzymatic recycling assay based on glutathione reductase ( F. Tietze, 1969 , Anal. Biochem. 27 , 502–522). In the original and several subsequent descriptions of this procedure, glutathione disulfide is selectively determined by assaying samples in which

Publisher Summary Glutathione reductase is a flavoprotein catalyzing the NADPH-dependent reduction of glutathione disulfide (GSSG) to glutathione (GSH). The reaction is essential for the maintenance of glutathione levels. Glutathione has a major role as a reductant in oxidation–reduction processes, and serves in detoxication and several other ...

The aim of this work was to study the temporare variation of oxidative stress in the plasma and erythrocytes (CR) of renal transplant patients We determined total glutathione (GST), as well as oxidized (GSSG) and reduced (GSH) fractions and the activity of glutathione peroxidase (G-px), glutathione reductase (G-red) and glutathione transferase (GSt ...
