Repair of damaged components, metal sequestration converts ₂ radical to #1₂02 and releaus Oy. catalane: Redull H/9, to H₂0, prevents hydroxy/ ladical tomation mostly in puoxisomes. a a 204 Vitamin E: Alpha-tocophuol * Lipid solube, protects against lipid peroxidation in membranes. * Nonentymatic terminator of free radical chain reaction Hamin C: Ascobale * Dorsales e-to vitamin E to regeneite Vitamin & * Water soluble, cinculates in blood and fluids to access membranes. * Redox co-enzyme for collagen syntheirs. GSH = 3.) Glutathione peroxidase, glutathione reductasa glutathione (Glycine, cyclube, glotamile) * peroxidane = reduces #₂0L, oxidizes 2 SH groups- GSSG in mitochondria, cytosol, howe selenium * Reduitare = recycles the glotathione, reduces NADPH 4) Treating mice with 1.284g seleniom /kg body weight significantly restored the namal levels of these parameters.
