, catalase
by catalyzing the decomposition of
hydrogen peroxide (H2
O2
) to water and
oxygen. Glutathione peroxidase is a
selenium containing enzyme which
catalyses the reduction of H2
O2
and lipid
hydroperoxide, generated during lipid
peroxidation, to water using reduced
glutathione as substrate. Selenium and
vitamin E both appear to be necessary for
efficient scavenging of peroxides from
cytosol and cell membrane, respectively.
Cu exerts its antioxidant activity through
the cytosolic superoxide dismutase. Zinc
is an element essential for normal growth,
reproduction and other different
functions of the body. It is a component
of several enzymes like cytosolic
superoxide dismutase, alcohol
dehydrogenase, alkaline phosphatase,
carbonic anhydrase, etc14.
