The glutathione peroxidase acts on peroxides in general, using glutathione as a cofactor, while superoxide dismutase catalyzes the dismutation of the superoxide radical anion ([O.sub.2]) to hydrogen peroxide ([H.sub.2][O.sub.2]) and [O.sub.2], and the catalase acts as a catalyst for the decomposition of [H.sub.2][O.sub.2] to [H.sub.2]O and [O.sub.2].

lore) dietician = nutrition logician-tactician-technician-physician dismutation = oxygenation/hydrogenation disproportionation leptonic = electronic, muonic, tauonic (the three classes of lepton) luminescence = fluorescence, phosphorescence (the two main types of luminescence) patination = carbonation, oxidation (carbonation on copper/bronze, oxidation on other metals) stutter = shutter-utter (coinage, automatic camera metaphor) xenation = nonrelation visitation (from Jeff Grant; xenation (OED, rare) = sojourning as a stranger)
The CAT is the enzyme that has a high potential in the [H.sub.2][O.sub.2] dismutation process into [H.sub.2]O and [O.sub.2], being essential for the ROS detoxification during the toxic radicals production conditions (Garg & Manchanda, 2009).
Actually the enzyme encoded by SOD1 gene destroys free superoxide radicals formed in the body by catalyzing the dismutation of superoxide into O2 and H2O2 (Borgstahl et al., 1996).
The reduced catalase activity says of a decreasing respond that prevents accumulation of hydrogen peroxide derived from dismutation of superoxide anion and aerobic oxidation of rehabilitated flavoproteins.
Superoxide dismutase is an enzyme responsible for dismutation of superoxide radical to hydrogen peroxide.
Superoxide dismutase is an enzyme catalyzing the dismutation reaction of superoxide radicals to hydrogen peroxide.
