Superoxide dismutase “SOD” is an enzyme that alternately catalyzes the dismutation or partitioning of the superoxide O2− radical.
It changes the radical O2− into ordinary molecular oxygen (O2) and hydrogen peroxide (H2O2).
Cu-Zn-SOD is most prevalent in human plasma known as the bovine Cu-Zn enzyme.
Super Oxide Dismutase enzymes (SODs) act as powerful antioxidants. SOD’s protect cellular components from being oxidized by reactive oxygen species (ROS).
A free radical or ROS is a superoxide molecular when O2 is reduced to O2−. It absorbs an excited electron released from compounds of the electron transport chain. SODs catalyze the production of O2 and H2O2 from superoxide (O2−).
Cu-Zn-SOD results in less harmful reactants to the cells, thus protecting the cell from superoxide toxicity.
