1 4 Superoxide is converted to hydrogen peroxide (H 2 O 2 ) by superoxide dismutase (SOD).

This niosome having a metal porphyrin complex embedded therein has an SOD activity and can target super oxide anion radical (O2-.) and surely decrease it.

Relationship between mitochondrial superoxide and hydrogen peroxide production and longevity of mammalian species.

It has been reported that there exists an inverse correlation between the rate of superoxide/hydrogen peroxide production by mitochondria and the maximum longevity of mammalian species.

The main free radical is the superoxide radical (O2-).

The agent can be used for decomposing excess superoxide anion or nitrogen monoxide in an organism with good efficiency.

helps neutralise free radicals and reactive oxygen species, particularly superoxide anion ;

These reactions involve the dismutation of superoxide anion to hydrogen peroxide by superoxide dismutase and the conversion of hydrogen peroxide to water by catalase.

In this process, the superoxide anion is produced as a by-product of several steps in the electron transport chain.

Superoxide dismutase (SOD): The anion superoxide O2− is the radical oxygen most abundantly formed by cells.
