Betaine reduction has so far only been studied with . (Naumann et al. 1983). The observed formation of trimethylamine was dependent on the presence of 1 µM selenite.

Dependence of Mouse Liver Phospholipid Hydroperoxide Glutathione Peroxidase on Dietary Seleniumity released the free fatty acid hydroperoxides (Grossmann and Wendel 1983), the PHGPx acts directly upon complex lipid hydroperoxides even in the heterogeneous phase, i.e., in the form of micelles (Ursini and Bindoli 1987). On the other hand, the enzymatic rate of PHGPx towards H.O. is poor compared to GSH-Px.

Active Oxygen Generation by the Reaction of Selenite with Reduced Glutathione in Vitro vitro hemolysis. In order to estimate the relationship between GSH and the selenite-induced lipid peroxidation, we have examined the active oxygen generation in the mixture of selenite and GSH by using luminol- or lucigenin-dependent chemiluminescence (CL) as an indicator.

GSH-Px protein contains a selenocysteine (Se-Cys) moiety in its active site, but the mechanism of Se-Cys incorporation into the polypeptide chain of the enzyme protein has long been unresolved. Chambers et al. (1986) discovered that a UGA termiation codon in the open reading frame of

However, growth on serine is independent of selenite addition as that on alan
