Unsaturated Lipide Oxidation Catalyzed by Hematin Compounds*
Hematin catalysis of unsaturated lipide oxidation is probably a primary reaction in many types of pathological unsaturated fat oxidation in viva (l-3) and in the spoilage of frozen meat products by oxidative fat rancidity (4). Some of the properties of hematin catalysis have been described (4-8), but knowledge of the reaction mechanism and the reaction products is relatively meager. The catalyt...

متن کاملElectrophilic Substitution of Aromatic Compounds by Unsaturated Sugar Derivatives
Glycals 1 and 2 react with methoxybenzene in the presence of SnCLj forming ^-substituted C-glycosyl compounds 4 and 5 + 6 respectively. Under similar conditions l -Obenzoylor methyl pent-2-enopyranos-4-uloses (7) and (8) react with electron rich aromatic compounds furnishing either C-glycosyl compounds or C-2 aryl substituted products depending on the nature of the aromatic component as well as...
متن کاملCarbonyl Compounds Enols and Enolate Ons. Unsaturated and Polycarbonyl Compounds
ome of the most useful reactions of carbonyl compounds involve carbonhydrogen bonds adjacent to the carbonyl group. Such reactions, which can be regarded as the backbone of much synthetic organic chemistry, usually result in the replacement of the hydrogen by some other atom or group, as in the I I I I sequence H-C-C=O -+ X-C-C=O. The important examples we I I will consider in this chapter are ...
متن کاملAlkylating potential of α,β-unsaturated compounds.
Alkylation reactions of the nucleoside guanosine (Guo) by the α,β-unsaturated compounds (α,β-UC) acrylonitrile (AN), acrylamide (AM), acrylic acid (AA) and acrolein (AC), which can act as alkylating agents of DNA, were investigated kinetically. The following conclusions were drawn: i) The Guo alkylation mechanism by AC is different from those brought about the other α,β-UC; ii) for the first th...
