glutathione peroxidase ppt Phospholipid Hydroperoxide - an overview The Selenoprotein Glutathione Peroxidase 4:

Model and physiological GSSR substrates are, for example, l-cysteine-glutathione disulfide (GSSCys) 9,10,11,12,13,14,15 , coenzyme A-glutathione disulfide 3,16 , as well as S -glutathionylated serum albumin 9,11,17,18,19,20 , sirtuin 21 , sulfiredoxin 22 , and peroxiredoxins 23,24,25,26,27,28,29

XO transfers hypoxanthine to xanthine or xanthine to uric acid accompanied by the formation of superoxide radicals

Whereas two S -glutathionylation sites were identified in A

Ex vivo , GSSG concentration can increase due to continued reduction of hydrogen peroxide by glutathione peroxidase and reaction with other reactive species
