[Kinetics of the interaction of ferrous oxide with oxidized lipids and possibility of chiluminescent determination of hydroperoxides].

The theory shows that for lipids containing hydroperoxides of unsaturated fatty acids there exists a verge concentration of Fe2+: at concentrations of Fe2+ lower than the verge one the peroxidation process develops autocatalytically and at higher concentrations it looks pulseshaped. In the second case the amplitude of pulse concentration of peroxide radicals and the square root from the maximum value of chemiluminescence intensity are proportional to the concentration of hydroperoxides present in the system at the time of ferrous ions injection. The former two values do not depend on the concentration of inoxidized fatty acids. In the experiments of chemiluminescence of partially oxidized linoleic acid and lecithin in methanol-benzene solutions (1 : 2) a perfect correlation between the experimental data and theoretical conclusions was revealed.
