  • carbon
  • The Dakin oxidation has two rate-limiting steps: nucleophilic addition of hydroperoxide to the carbonyl carbon and [1,aryl migration. (wikipedia.org)
  • Therefore, the overall rate of oxidation is dependent on the nucleophilicity of hydroperoxide, the electrophilicity of the carbonyl carbon, and the speed of [1,aryl migration. (wikipedia.org)
  • Partial oxidation of carbon produces carbon monoxide, nitrogen-containing materials can yield hydrogen cyanide, ammonia, and nitrogen oxides. (wikipedia.org)
  • Tyrosine can either undergo a decarboxylation via tyrosine decarboxylase to generate tyramine and subsequently undergo an oxidation at carbon 3 by a monophenol hydroxylase or first be hydroxylated by tyrosine hydroxylase to form L-DOPA and decarboxylated by DOPA decarboxylase. (wikipedia.org)
  • The product, methylated at the two meta positions with respect to the alkyl substituent, experiences a final methylation at the 4 carbon by a guaiacol-O-methyltransferase, which also operates by a SAM-dependent mechanism. (wikipedia.org)
  • fungi
  • Food preservation is to prevent the growth of microorganisms (such as yeasts), or other microorganisms (although some methods work by introducing benign bacteria or fungi to the food), as well as slowing the oxidation of fats that cause rancidity. (wikipedia.org)
  • enzyme
  • After all of the experiments that we ran we could conclude the enzyme oxidation rate (mmoles/min) depending on the amount of each product that was used in a single cubit test tube. (studymode.com)
  • however, it is more commonly associated with ethanol oxidation catalysed by the enzyme ethanol dehydrogenase. (wikipedia.org)
  • reaction
  • The present study was first aimed at a complete steady-state kinetic analysis of the reaction between guaiacol (2-methoxyphenol) and the myeloperoxidase (MPO)/H 2 O 2 system, including a description of the isolation and purification of MPO from human polymorphonuclear neutrophil cells. (biochemj.org)
  • The final product of NADPH oxidation was shown to be enzymically active NADP + , while guaiacol was generated continuously from the reaction between NADPH and oxidized guaiacol product. (biochemj.org)
  • BQ, in itself, was able to spontaneously oxidize NADPH, but neither the rate nor the stoichiometry of the reaction could account for the NADPH-oxidation process involved in the steady-state peroxidation cycle. (biochemj.org)
  • These results provide evidence that the oxidation of NADPH does not involve a free nucleotide radical intermediate, but that this is probably due to a direct electron-transfer reaction between NADPH and a two-electron-oxidized guaiacol intermediate. (biochemj.org)
  • The Dakin oxidation, which is closely related to the Baeyer-Villiger oxidation, is not to be confused with the Dakin-West reaction, though both are named after Henry Drysdale Dakin. (wikipedia.org)
  • rate
  • Under these conditions, the stoichiometry of NADPH:H 2 O 2 is 1, and the oxidation rate of NADPH approximates to that of the rate of guaiacol oxidation by MPO. (biochemj.org)
  • Spectrophotometer (record results of oxidation rate over two minutes. (studymode.com)
  • After each test tube is filled with all of the samples, the cuvette is immediately covered with perafilm and inserted in the spectrophotometer to be recorded for guaiacol oxidation rate over two minutes (A/min). (studymode.com)

  • DRUM quantity approximately 50 kg Biochem/physiol Actions Guaiacol, along with 2,4,6-trichloroanisole, is responsible for cork taint in wine. (thomassci.com)
  • results
  • These results were recorded by taking the materials in a test tube, then inserting them into a spectrophotometer to record the oxidation (intensity of color change from clear to reddish-brown) over a course of two minutes to observe color change. (studymode.com)
  • Then the results of oxidized guaiacol was measured and recorded over a course of two minutes. (studymode.com)
