1. Modern catechol developing was pioneered by noted photographer Sandy King. 2. The overall reaction of catechol 1, 2-dioxygenase. 3. Unlike borane itself or alkylboranes, catechol borane exists as a monomer. 4. Many of these active ingredients work through inhibiting catechol oxidase. 5. Estradiol is also metabolized via hydroxylation into catechol estrogens. 6. Tyrosinases and catechol oxidases are collectively termed polyphenol oxidases. 7. Hydroquinone, benzenetriol and catechol are converted to polyphenols. 8. This process is catalyzed by catechol O-methyltransferase methylates ( COMT ). 9. According to his information, urushiol is a mix of substances called catechol derivatives. 10. Aside from sulfate conjugation, EE is mainly metabolized by hydroxylation into catechol estrogens.
