The Generation of Semiquinone Radical Using Laccase/ O_2 System 漆酶/O2体系获取半醌自由基的研究
The Kinetic Simulation Study of Laccase Catalyzed Formation and Decay of Semiquinone Radicals 漆酶催化半醌自由基中间体动力学的模拟研究
A review is given on the method for the effective generation of high steady state concentration of semiquinone radicals established in three ways using laccase/ O 2 system in static condition. 本文综述了在静态条件下用漆酶/O2体系获取高稳定浓度半醌自由基阴离子的有效办法。
Detection of Semiquinone Radical Anions of Hypocrellins by ESR Spectra ESR方法检测竹红菌素的半醌负离子自由基
The semiquinone radical of TS as reduction product existed stably on CPE, which might be that hydrophobic organic phase inhibited the disproportionation reaction of the radical of TS. 还原产物半醌自由基能稳定存在,这可能是由于CPE中疏水有机相阻止了该自由基的岐化反应。
In DMF tetraethyl ammonium bromide ( TEAB) media, the reduction of irisquinone was two successive single electron processes without the chemical reaction of the free radical semiquinone. 在DMF-四乙基溴化铵(TEAB)质子惰性介质中,马蔺子素连续两步单电子还原生成相应氢醌阴离子,无中间体半醌自由基的化学反应发生。
Measuring the molar extinction coefficient of semiquinone and the protonation constants of the color developer CD-4 彩色显影剂CD-4质子化常数和半醌摩尔吸光系数的测定
The ESR study of the reaction system showed that this sulfonationreaction was initiated by the heat induced electron transfer between Hypocrellins and SO_2~ ( 2-) to produce the semiquinone radical anion and sulfur trioxide radical anion ( SO_3~-). 反应体系的ESP研究表明,这一磺化反应首先是通过竹红菌素和Na2SO3之间热活化的电子转移进行的。
The study found that juglone rapidly oxidation Single-electron to semiquinone free radicals. 研究发现胡桃醌经快速的单电子氧化还原成半醌自由基。
