diphenols造句

• The company also produces ethyl vanillin, diphenols and fine chemicals.
• In plants, both enzymes can catalyze the oxidation of ortho-diphenols substrates into their corresponding ortho-quinones.
• Polyphenol oxidase ( PPO ) is an enzyme that catalyses the oxidation of o-diphenols to produce o-quinones.
• This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with other acceptors.
• This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with oxygen as acceptor.
• This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with a cytochrome as acceptor.
• Caffeic acid and related " o "-diphenols are rapidly oxidized by " o "-diphenol oxidases in tissue extracts.
• This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with NAD + or NADP + as acceptor.
• The key difference between the two related enzymes is that tyrosinase can catalyze the hydroxylation of monophenols to diphenols ( monophenolase activity ) as well as the oxidation of the o-diphenol to the o-quinone ( diphenolase activity ) whereas catechol oxidase only possesses diphenolase activity.
• And of course, the further away the two groups are from each other, the weaker the inductive effect, so it's why the para-diphenol would have the highest pka's of all the diphenols, while the meta-diol would barely see any mesomeric effect and mostly see the inductive effect.
