硒化合物对羟基自由基作用的研究

A STUDY ON SCAVENGING EFFECT OF SELENIUM COMPOUNDS UPON HYDROXYL RADICAL WITH SPIN TRAPPING

本文选用硒代蛋氨酸(Se-Met)和无机硒化合物,采用自旋捕集技术,在温和条件下进行硒化合物与羟基自由基作用的ESR研究。实验结果表明,硒化合物对羟基自由基具有清除作用。

The direct interaction of selenium compounds(selenomethionine and sodium selenitc) with hydroxyl radicals were studied in a moderate conditions by means of spin trapping technique. The experimental results show that the selenium compounds can scavenge hydroxyl radicals.
