One unit is defined as the amount of enzyme needed to exhibit 50% dismutation
of the radical superoxide.
Catalase activity was measured using colorimetric methods based on the dismutation
SOD is involved in the dismutation
of super oxide radical to either molecular oxygen or to hydrogen peroxide.
In addition to uncoupling, peroxynitrite formation can also occur when levels of nitric oxide are so high that superoxide dismutase is overcome and can no longer provide dismutation
activity (Vinten-Johansen, 2000).
Superoxide ions can inactivate calatalse enzyme, resulting in decreased dismutation
of hydrogen peroxide, and consequently, increase in [H.
superoxide dismutase (SOD) catalyses the dismutation
of superoxide to [H.
Cytozylic CuZn-dismutase superoxide catalyses the reaction of dismutation
of superoxide anion to less reactive hydrogen peroxide and molecular oxygen :
Superoxide dismutase (SOD) is an endogenous enzyme responsible for the dismutation
of superoxide radicals.
Superoxide anion can also undergo dismutation
to form hydrogen peroxide ([H.
SOD and catalase catalyze the dismutation
of superoxide and hydrogen peroxide, respectively.
6) Superoxide dismutase, which catalyses the dismutation
of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is considered to be the essential enzyme in the defense against the toxic effects of [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII].
Catalase employs a two-electron transfer in the dismutation
of hydrogen peroxide ([H.
