• ALDH
  • Interpretation & conclusions: PartySmart enhanced acetaldehyde metabolism by increasing ADH and ALDH activity without any side effects. (redorbit.com)
  • Despite the name "dehydrogenase", their mode of oxidation is by addition of oxygen rather than by removal of hydrogen - that is, they convert aldehydes (R-C(=O)-H) to carboxylic acids (R-C(=O)-O-H). To date, nineteen ALDH genes have been identified within the human genome. (wikipedia.org)
  • ketones
  • The most common peroxyacyl radical is peroxyacetyl, which can be formed from the free radical oxidation of acetaldehyde, various ketones, or the photolysis of dicarbonyl compounds such as methylglyoxal or diacetyl. (wikipedia.org)
  • Byproducts of the dehydrogenation include diethyl ether, which is thought to arise primarily due to aluminum sites in the catalyst, acetaldehyde and its aldol products, higher esters, and ketones. (wikipedia.org)
  • reaction
  • The influence of the nature of the saturating cation as well as the clay pretreatment on this oxidation process are discussed and reaction pathways are proposed. (clays.org)
  • Finally, by using the cyclic voltammetry, chronoamperometric and tafel plots method, the catalytic rate constant, charge-transfer coefficient, the number of electrons involved in the rate-determining step (nα) and exchange current density for chemical reaction of acetaldehyde was estimated as 0.356 × 104 cm3 mol-1 s-1, 0.51, 1 and 2.76×10-8 Acm-2 respectively.

  • For example, reaction with sodium hydroxide produces sodium selenite: SeO2 + 2 NaOH → Na2SeO3 + H2O Selenium dioxide is prepared by oxidation of selenium by burning in air or by reaction with nitric acid or hydrogen peroxide, but perhaps the most convenient preparation is by the dehydration of selenous acid.

  • This type of reaction is called a Riley oxidation. (wikipedia.org)
  • The MEOS pathway converts ethanol to acetaldehyde by way of a redox reaction. (wikipedia.org)
  • As part of the ensuing research effort, a reaction of ethylene and oxygen over palladium on carbon in a quest for ethylene oxide unexpectedly gave evidence for the formation of acetaldehyde (simply based on smell). (wikipedia.org)
  • The reaction mechanism for the industrial Wacker process (olefin oxidation via palladium(II) chloride) has received significant attention for several decades. (wikipedia.org)
  • intermediate
  • Utilized in the bacterial degradation of toxic aromatic compounds, the enzyme's crystal structure indicates that intermediates are shuttled directly between active sites through a hydrophobic intermediary channel, providing an unreactive environment in which to move the reactive acetaldehyde intermediate from the aldolase active site to the acetaldehyde dehydrogenase active site. (wikipedia.org)
  • redox
  • Moreover the altered redox state impairs gluconeogenesis, diverts acetyl-CoA toward ketogenesis and fatty acid synthesis, and diminishes lipid oxidation disrupting fatty acids β -oxidation [ 7 ]. (hindawi.com)
  • substrate
  • This would be considered an oxidation of the substrate, in which the substrate either loses hydrogen atoms or gains an oxygen atom (from water). (wikipedia.org)
  • pathway
  • Thiamine pyrophosphate is also a coenzyme of the transketolase system by which direct oxidation of glucose occurs in the cytoplasm of cells via the pentose phosphate pathway. (fao.org)
  • liver
  • Most of the protein in the liver exists in a form with xanthine dehydrogenase activity, but it can be converted to xanthine oxidase by reversible sulfhydryl oxidation or by irreversible proteolytic modification. (wikipedia.org)
  • symptoms
  • Accumulation of acetaldehyde leads to the development of physical symptoms of hangover, which include fatigue, headache, increased sensitivity to light and sound, redness of the eyes, muscle aches, and thirst3. (redorbit.com)
  • higher
  • The metabolized acetaldehyde in the blood, which is six times higher than in individuals without the mutation, has shown to be a carcinogen in lab animals. (wikipedia.org)
  • activity
  • The modified electrode exhibited remarkable electrocatalytic activity for the oxidation of acetaldehyde under alkaline conditions, indicating that the anodic oxidation of acetaldehyde could be catalyzed at Ni/Al LDH-SGD-CC electrode. (ac.ir)
  • The photocatalytic activity of two commercial titanium dioxide powders (Cristal Global, Millennium PC500 and Evonik, P25) is compared towards acetaldehyde degradation in the gas phase. (uantwerpen.be)
