Lipid hydroperoxides in plants.
Hydroperoxides are the primary oxygenated products of polyunsaturated fatty acids and were determined spectrophotometrically based on their reaction with an excess of Fe2+ at low pH in the presence of the dye Xylenol Orange. Triphenylphosphine-mediated hydroxide formation was used to authenticate the signal generated by the hydroperoxides. The method readily detected lipid peroxidation in a ran...
متن کاملPreparation of pure lipid hydroperoxides.
Increasing evidence of lipid peroxidation in food deterioration and pathophysiology of diseases have revealed the need for a pure lipid hydroperoxide (LOOH) reference as an authentic standard for quantification and as a compound for biological studies in this field. Generally, LOOH is prepared from photo- or enzymatically oxidized lipids; however, separating LOOH from other oxidation products a...
متن کاملOxidation of D-(-)-Ribose with H20 2 and Lipid Hydroperoxides
D-(-)-ribose was subjected to oxidation with equimolar amounts of H20 2/Fe2+ and 13-hydroperoxy-9-c/s-l l-fra/75-octadecadienoic acid/Fe2+. Smaller carbohydrates, carbonyl compounds, hydroxy acids and polyols were produced. Identification of carbonyl compounds was achieved by trapping with pentafluorobenzylhydroxylamine hydrochloride (PFBHA-HC1). All products were identified by GC/MS after deri...
متن کاملCiprofloxacin increases hepatic and renal lipid hydroperoxides levels in mice.
Ciprofloxacin (CFX) is an effective and relatively safe antimicrobial used in a variety of human infections. However, adverse drug reactions and positive results in genotoxic tests are reported. In order to understand the possible pathophysiological mechanisms of the toxic effects informed for CFX, lipid hydroperoxides (LOOH) -oxidative mediators of peroxidation- were quantified in liver and ki...
