Catechin-Catechin is a tannin peculiar to green tea because the black tea fermentation process reduces catechins in black tea. Catechin is a powerful, water soluable polyphenol and antioxidant that is easily oxidized.
Catechol oxidase is an enzyme that catalyses the oxidation of phenols such as catechol. Catechol oxidase is a copper-containing enzyme whose activity is similar to that of tyrosinase, a related class of copper oxidases.They are ubiquitous plant enzymes that catalyze oxidation of a broad range of ortho-diphenols to the corresponding o-quinones coupled with the reduction of oxygen to 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.
