Modeling the sensory impact of defined combinations of volatile lipid oxidation products on fishy and metallic off-flavors.
J. Agric. Food Chem. 52(6) , 1635-41, (2004) The volatiles (E,Z)-2,6-nonadienal, 1-penten-3-one, (Z)-4-heptenal, and (E,E)-2,4-heptadienal were added to milk containing 1.5% fat according to a central composite design, to evaluate the individual and combinatory effects of these volatiles on sensory prop... |

Inhalation toxicity studies of the alpha,beta-unsaturated ketones: ethyl vinyl ketone.
Inhal. Toxicol. 13(8) , 633-58, (2001) The National Toxicology Program is conducting a chemical class study to investigate the structure-activity relationships for the toxicity of alpha,beta-unsaturated ketones. Ethyl vinyl ketone (EVK) was selected for study because it is a representative straigh... |

Rapid access to 2'-branched-carbocyclic nucleosides and their 4'-epimers from 2-alkyl-cyclopentene-1-ones.
Nucleosides Nucleotides Nucleic Acids 24(5-7) , 695-9, (2005) 2-Methyl-2-cyclopentene-1-one was used as starting material in a novel route toward 2'-branchedcarbocyclic nucleosides. This methodology was efficiently adapted to the preparation of 4'-epicarbocycles. A series of this new class of molecules was synthesized a... |

Tolerance to 1-pentene-3-ol and to 1-pentene-3-one in relation to alcohol dehydrogenase (ADH) and aldo keto reductase (AKR) activities in Drosophila melanogaster.
Biochem. Genet. 28(9-10) , 513-22, (1990) The detoxification of 1-pentene-3-ol (pentenol) and 1-pentene-3-one (pentenone) by Drosophila melanogaster adult flies has been studied in two homozygous lines for the AdhF and AdhS alleles (LRC lines), in their respective lines selected for tolerance to etha... |

Identification and characterization of deoxyguanosine adducts of methyl vinyl ketone and ethyl vinyl ketone. Genotoxicity of the ketones in the SOS Chromotest.
Chem. Res. Toxicol. 4(1) , 50-7, (1991) The reaction of the alpha, beta-unsaturated ketones methyl vinyl ketone (MVK) and ethyl vinyl ketone (EVK) with nucleosides and 5'-mononucleotides was studied. The genotoxic activity of MVK and EVK in the SOS Chromotest was investigated. Three different types... |

Photooxidation of leaf-wound oxygenated compounds, 1-penten-3-ol, (Z)-3-hexen-1-ol, and 1-penten-3-one, initiated by OH radicals and sunlight.
Environ. Sci. Technol. 43(6) , 1831-7, (2009) An evaluation of the environmental impact of stressed-induced compounds, 1-penten-3-ol,(Z)-3-hexen-1-ol, and 1-penten-3-one (ethyl vinyl ketone, EVK), is presented in this paper. The removal processes considered here are the gas-phase reactions with hydroxyl ... |

Comparison of tomatillo and tomato volatile compounds in the headspace by selected ion flow tube mass spectrometry (SIFT-MS).
J. Food Sci. 75(3) , C268-73, (2010) The concentration of 31 volatiles were measured in the headspace of tomatillos using selected ion flow tube-mass spectrometry (SIFT-MS), and were compared with those in vine-ripened tomato, roma tomato, cherry tomato, and grape tomato. None of the volatiles w... |
