• quinones
  • Cyclic esters are formed upon treatment with phosphorus trichloride and phosphorus oxychloride, carbonyl chloride, and sulphuryl chloride: C6H4(OH)2 + XCl2 → C6H4(O2X) + 2 HCl where X = CO, SO2, PCl, P(O)Cl Catechols produce quinones with the addition of ceric ammonium nitrate (CAN).

  • structure
  • The crystal structure of catechol oxidase purified from Ipomoea batatas has been resolved in its active form in both the oxidized Cu(II)-Cu(II) state and the reduced Cu(I)-Cu(I) state. (wikipedia.org)
  • Urushiols are naturally existing organic compounds that have the catechol skeleton structure and diphenol functionality but with alkyl groups substituted onto the aromatic ring. (wikipedia.org)
  • Catecholamines are biochemically significant hormones/neurotransmitters that are phenethylamines in which the phenyl group has a catechol skeleton structure. (wikipedia.org)
  • contains
  • Catechol oxidase is nuclear-encoded, and its N-terminal end contains a signal peptide that directs the protein to the chloroplast thylakoid lumen, where it can either be soluble or loosely associated with the thylakoid membrane. (wikipedia.org)
