摘要:
类胡萝卜素有多种生物学作用,包括抑癌防衰、减低一些疾病发生.其重要原因之一是它们的生物抗氧化剂特性:猝灭1O2、清除自由基、抑制脂类过氧化与细胞呼吸爆发的抗氧化作用.采用H2O2-NaOCl体系产生的1O2的发光法研究1O2的猝灭作用,脉冲辐解法研究与CCl3OO@ 的反应,测定自由基引发的亚油酸甲酯氢过氧化物生成和脂质体过氧化产物硫代巴比妥酸反应物生成研究抑制脂质过氧化,通过依赖于鲁米诺的化学发光法与无细胞模拟体系研究对巨噬细胞呼吸爆发的影响.研究表明:类胡萝卜素通过物理过程猝灭1O2,与CCl3OO@
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 @
