[Phosphorescent analysis of lipid peroxidation products in isolated human erythrocyte membranes].
The room temperature phosphorescence of lipid peroxidation products in the composition of isolated human erythrocyte membranes was registered, and its kinetic parameters were determined. The excitation and emission spectra of phosphorescence of lipid peroxidation products in the composition of erythrocyte membranes at 0 degree C measured. The nature of lipid peroxidation products possessing the phosphorescencing capacity was discussed. Based on the analysis of temperature dependences of the intensity and lifetimes of phosphorescence of lipid peroxidation products in the range -2 divided by 26 degrees C, it is concluded that the deactivation of excited triplet states of lipid chromophores was realized by the dynamic type.
