General FunctionPhospholipid-hydroperoxide glutathione peroxidase activity
Specific FunctionProtects cells against membrane lipid peroxidation and cell death. Required for normal sperm development and male fertility. Could play a major role in protecting mammals from the toxicity of ingested lipid hydroperoxides. Essential for embryonic development. Protects from radiation and oxidative damage.
