peroxidase
Peroxide-breaking protein
Peroxidase is an enzyme that catalyzes reactions using hydrogen peroxide or similar compounds to oxidize other substances.
Found throughout living organisms, peroxidases help break down toxins and regulate cell processes.
In laboratory work, they're widely used as markers in diagnostic tests: The test uses horseradish peroxidase to detect antibodies.
