Definition
English
:
Highly reactive compounds produced when
oxygen
is reduced by a single electron. In biological systems, they may be generated during the normal catalytic function of a number of
enzymes
and during the
oxidation
of hemoglobin to
METHEMOGLOBIN
. In living organisms,
SUPEROXIDE DISMUTASE
protects the cell from the deleterious effects of
superoxides.
