螯合

A new chelating fiber containing thioamide group is synthesized by cross-linking of polyacrylonitrile fiber with ethylene-dimine and following with chemical modification with sodium sulfide using DMF as solvent.

以腈纶纤维为起始原料，经乙二胺预交联后，以DMF作溶剂与硫化钠反应，合成了一种硫代酰胺功能基可达6.8mmol/g干纤维的螯合功能纤维，其对贵金属金、银离子具有良好的吸附性能。

The results are following:(1)We investigated the influence of the positional isomeric effect on structures.Due to the less space-crowding,it is easier for 3-pytpy to behave as bridging ligand than 2-pytpy under the same reaction conditions,while,it is easier for 2-pytpy to function as tridentate chelating ligand to construct supramolecular structures.

研究结果如下：(1)研究了两个吡啶取代三联吡啶配体的位置异构效应对配合物结构的影响。3-pytpy配体比2-pytpy具有更小的空间位阻，在相同的合成条件下容易以单-三齿桥联方式配位；而2-pytpy更易以三齿螯合形式配位，通过π…π堆积作用形成超分子结构。

It showed that it has better effect by using 50% ethanol to be solvent to extract Vitaceae plants than other solvents.

在抗氧化实验中：细本山葡萄及乌蘝莓在螯合亚铁离子的能力中效用分别有达到70%及60%以上。

In result of DPPH free radical clean test, we got good effect that using 50% ethanol and ethanol extracted Vitaceae plants in the test of ferrous ion chelating effects have over 50% restraint rate by using 50% ethanol.

在清除DPPH自由基方面结果显示，用乙醇及50%乙醇萃取的葡萄科植物具有不错效用，其中50%乙醇萃取细本山葡萄在还原能力测定及螯合亚铁离子实验中皆达到50%以上的抑制率。

In this experiment, we use different kind of solvent to extract Vitaceae plants to test of antioxidae, includes clean DPPH free radical, ferrous ions chelating effects, restrain producing superoxide anion, ferric reducing ability of plasma and anti-liver lipid peroxidation assay.

在利用不同溶媒萃取葡萄科植物评估抗乳癌细胞株MCF-7毒杀试验和抗氧化试验中，其包含清除DPPH自由基、螯合亚铁离子、抑制超氧阴离子之生成、还原三价铁离子能力测定及抗肝脂质过氧化等几项。

Whereafter oxidated to be Fe3, finally, turned to be Fe2O3 deposit.

其次，研究了甘氨酸螯合铁在营养强化面粉中的应用。

The expressions of many plant metallothionein genes under environmental stresses suggested that they may function in both metal chaperoning and scavenging of reactive oxygen species with their large number of cysteine residues to protect plants from oxidative damage.

很多实验表明，植物金属硫蛋白可以通过其大量的Cys残基螯合重金属并清除活性氧，使植物避免氧化损伤。

NO one else has Chelated Minerals, the highest form of minerals for absorption.

从来没有人螯合矿物，为吸收矿物的最高形式。

Bull; ANY METAL THAT IS IONIZED IN pH NEUTRAL WATER COULD NOT BE EXPECTED TO BE CHELATED IN THE GUT.

bull；任何金属，在 pH 中性的水中是自由的离子，那么在肠道里不可能是螯合的

Amino acids chelated iron are usually synthesized in solution,it takes a long time and has liquid wastes.

氨基酸亚铁螯合物的合成普遍采用液相技术，合成时间长，存在废液污染。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
