- Abstract:
-
Carotenoids have a variety of biological effects, including inhibiting cancer and preventing aging, and reducing the occurrence of some diseases. One of the important reasons for this is their biological antioxidant properties: quenching 1O2, scavenging free radicals, inhibiting lipid peroxidation and antioxidant effects of cellular respiration bursts. The quenching effect of 2O2 was studied by luminescence method of 1O2 generated by H1O2-NaOCl system, the reaction with CCl3OO@ by pulse irradiation method was used to determine the formation of methyl linoleate hydroperoxide triggered by free radicals and the formation of thiobarbituric acid reactants in liposomal peroxidation products, and the effect on macrophage respiratory bursts was studied by chemiluminescence and cell-free mimicry system relying on luminol. Studies have shown that carotenoids quench 1O2 through physical processes, with CCl3OO @
