Selenium functions as a cofactor for antioxidant enzymes such as glutathione peroxidases and thioredoxin reductase.

(High-Selenium Baker's Yeast, NCI Thesaurus)

Hexylresorcinol may also inhibit oxidative DNA damage by enhancing the activity of antioxidant enzymes, including glutathione peroxidase and glutathione reductase, which facilitate scavenging reactive oxygen molecules by glutathione (GSH).

(Hexylresorcinol, NCI Thesaurus)

This allele, which encodes glutathione peroxidase 1 protein, is involved in detoxification of hydrogen peroxide.

(GPX1 wt Allele, NCI Thesaurus)

Selenium functions as a cofactor for antioxidant enzymes such as glutathione peroxidases and thioredoxin reductase, which protect cells from the free radical damage.

The complexity of the chemical structure of lignin can be explained by random polymerizations involving one of four main phenoxyl radicals formed upon the action of peroxidase.

(Lignin, NCI Thesaurus/CRCH)

Glutathione is also important as a cofactor for the enzyme glutathione peroxidase, in the uptake of amino acids, and in the synthesis of leukotrienes.
