A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take place. Specifically, they promote the oxidation of various compounds using naturally occurring peroxides, especially hydrogen peroxide (H 2 O 2), which are reduced, forming water.n fact, most of the the people that receive positive results on a thyroid peroxidase test (somewhere between 70 -90%) do indeed have chronic thyroidosis, however there are a some auto-immune disorders that can cause a false positive as well.
Catechol oxidase carries out the oxidation of phenols such as catechol, using dioxygen (O 2). In the presence of catechol, benzoquinone is formed (see reaction below). Hydrogens removed from catechol combine with oxygen to form water.atechol is present in small quantities in the vacuoles of cells of many plant tissues. Catechol oxidase is present in the cell cytoplasm. If the plant tissues are damaged, the catechol is released and the enzyme converts the catechol to ortho-quinone, which is a natural antiseptic.
