氧化还原

Experiments indicated that the oxidative ability of ocean manganese nodules is stronger than pure MnO 2 and the reductibility of aniline is stronger than phenol.

实验表明，大洋锰结核的氧化能力强于纯的MnO2，苯胺的还原性强于苯酚。

The reduction of insoluble quinones to soluble hydroquinones and reoxidation in air to the quinone structure is the principle involved in dyeing cloth with"vat" dyes.

瓮染燃料对布料着色的原理在于不溶性醌类的还原和可溶性氢醌于空气中被再氧化至醌类结构。

Due to the ability to reduce radicals, CDH is suggested to reduced phenoxyl radicals produced in lignin degradation and prevent their repolymerization to promote lignin degradation by ligninases.

由于CDH具有还原各类自由基的能力，因此可以推测在木素降解过程中CDH可能起还原木素酶氧化的中间产物苯氧自由基，从而阻止其再聚合，推动了木素的降解。

A series of mono-, sesqui-, di- and tri-terpenoids with various structural types, which produced by bio- oxidation, hydrogenation, hydrolyzation, esterification and cyclic cleavage toward-limenone, were analyed by GC-MS.

经GC-MS分析发现该两细菌对-柠檬烯有显著的生物催化转化作用，能对底物进行不同程度的氧化、还原、水解、酯化、开环等反应，并产生丰富的系列结构不同的其它萜类化合物：包括单萜、倍半萜、二萜、以及三萜等。

There were no changes in the hydroperoxides level or the ferric-reducingability for the laparoscopic sigmoidectomy with sevofluraneanesthesia, indicating that this procedure does not increasesurgical oxidative stress.

七氟醚麻醉腹腔镜下乙结肠切除术中过氧化氢水平和铁还原能力没有改变，这表明腹腔镜手术不会增加手术的氧化应激反应。

RESULTS: Ferric-reducing ability decreased significantly duringsurgery for the open sigmoidectomy with sevoflurane anesthesia,by 387 ± 153 mmol/L, though the hydroperoxides leveldid not change, showing that oxidative stress increases in surgicalpatients.

结果：七氟醚麻醉开腹乙结肠切除手术中铁还原能力显著减弱，减幅387 ± 153 mmol/L ，尽管过氧化氢水平没有改变，这表明手术增加了氧化应激。

A functionalized superparamagnetic iron oxide nanoparticles were synthesized by reduction-precipitation method, and were modified by silicane coupling agent. The nanoparticles were evaluated by diffraction, scanning electron microscope and X-ray energy spectrometer.

用部分还原－共沉淀法制备了四氧化三铁Fe3O4纳米材料，用硅烷偶联剂进行了表面修饰，用扫描电镜，X-射线粉晶衍射，磁强计，X射线能谱仪等分析仪器对材料的相关性能进行了测定。

Therefore, we characterized the Cyt c P71H/M80V variant protein electrochemically and spectroscopically. All the experimental results showed that the introduced histidine at position 71 did not act as a functional distal-histidine, but most likely coordinated to the heme iron, maybe due to the flexibility of theΩloop segment (resides 70-84) of Cyt c protein.

于是我们对P71H／M80V蛋白性质进行了一系列的研究，结果表明可能是由于Cyt c中Ωloop D肽段(residues 70-84)具有很强的柔韧性，使得His71并没有象HRP中的distal histidine一样起到酸碱催化功能，而是与heme发生了配位作用，无论是在氧化态还是还原态都成了heme的第六轴向配体。
