  • oxidation
  • In this work, acetaldehyde, propanal, and 2-propenal (acrolein) oxidation was investigated at low-temperature combustion condition (500-700 K). The isomer specific products concentrations as well as the time-resolved profiles were studied using Sandia's multiplexed photoionization mass spectroscopy (MPIMS) with synchrotron radiation from the Advanced Light Source (ALS). (asme.org)
  • In acetaldehyde oxidation, the formation of the main products are associated with HO 2 elimination channel from QOOH or direct H atom elimination from the parent radicals. (asme.org)
  • In propanal oxidation, the most intensive signal peak was associated with acetaldehyde (m/z=44) which was formed through the reaction of α′-R with O 2 . (asme.org)
  • metabolism
  • Mitochondrial metabolism requires inward and outward flux of hydrophilic metabolites, including ATP, ADP and respiratory substrates, through voltage-dependent anion channels (VDACs) in the mitochondrial outer membrane. (aspetjournals.org)
  • alcohols
  • Photolysis of heptanal in conditions resembling atmospheric conditions results in the formation of 1-pentene and acetaldehyde in 62% chemical yield together with cyclic alcohols (cyclobutanols and cyclopentanols) both from a Norrish type II channel and around 10% yield of hexanal from a Norrish type I channel (the initially formed n-hexyl radical attacked by oxygen).

  • 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)
  • The insertion of the CH radical into a C-H bond of the methyl group of acetaldehyde is likely to lead to a C3H5O reaction intermediate that can isomerize by β-hydrogen transfer of the aldehydic hydrogen atom and dissociate to form acrolein + H or ketene + CH3, which are observed directly.

  • α′-RO 2 intermediate decomposes to acetaldehyde+OH+CO via Waddington mechanism and formation of five-member ring transition state. (asme.org)
  • reaction
  • The ΔrG′ m value of this reaction is − 0.1 kJ/mol (Fig. 1 ) and would thus require either a high ratio of acetyl-CoA to acetaldehyde or NAD(P)H to NAD(P) (or both) in order to proceed towards ethanol production. (biomedcentral.com)
