生物合成

In recent years, with the development of various good catalysts especially the ruthenium alkylidenes bearing N-heterocyclic carbene ligands, the RCM reaction has been applied widely in the synthesis of complex organic molecules, biological molecules and natural products etc. The Nobel Prize in Chemistry 2005 goes to Yves Chauvin, Robert H.

近二，三十年来，随着各种性能优良的催化剂的不断发展，尤其是含氮杂环卡宾配体的钌催化剂的出现，关环复分解反应在合成复杂有机分子，生物活性大分子以及天然产物等方面已得到了极为广泛的应用。2005 年的诺贝尔化学奖分别授予了 Yves Chauvin，Robert H。

Mullis received a doctorate in 1979, after the biotechnology company Cetus engaged in the work of oligonucleotide synthesis.

This suggests that bacterial chemosynthesis is not a sufficient source of nutrition for these creatures.

这意味着细菌化学合成作为一种食物来源对这些生物并不充分。

It has great application values in the research field of chemosynthesis, developing new function materials and biologic materials.

在化学合成、新功能材料制备、生物材料等研究领域具有诸多应用价值。

We now know that chloramphenicol specifically affects the ribosomes of prokaryotic cells, thus inhibiting protein synthesis.

现在我们知道抗生素对原核生物细胞中的核糖体有特殊效应，从而能抑制其蛋白质的合成。

And among substrates including 2'-chloroacetophenone, 3'-chloroacetophenone, 4'-chloroacetophenone and 3-chloropropiophenone, the highest productivity of the reduced product with S. cerevisiae B5 was observed for 2'-chloroacetophenone.

许多研究者都在致力于研究和开发产物转化率高、手性选择性好的手性化合物合成路线，其中生物转化法由于其温和的反应条件及高度的手性选择性而受到人们的青睐。

In order to get a sufficient amount of the compound for further biological investigations, we therefore initiated a program to synthesize this target molecule.

为了获得足够数量的样品进行进一步的生物活性研究，立项对其进行化学合成。

In this dissertation, a series of cluster galactosides and cluster mannoside s were synthesized, which target asialoglycoprotein receptor and plant lectin Concanavalin A respectively.

本论文以肝细胞表面受体和植物凝集素Con A为靶点，研究了多价半乳糖簇和甘露糖簇的合成及生物活性。

Target compounds have been synthesized by condensation of the aromatic nucleus and amino heterocylcle with acyl isocyanates or acylisothiocyanates in absolutely anhydrous and aprotic solvent.

为了寻找高活性的农药品种，利用生物等排原理和亚结构连接法，对脲类化合物的母体结构进行了修饰，将芳氧羧酸类及吡唑环引入酰基脲母体结构中，利用酰基异氰酸酯与杂芳环胺类化合物在无水非质子溶剂中发生亲核加成反应，合成了四个系列21种新的酰基脲类目标化合物。

Systems biology includes the omics, computational and synthetic biotechnology. An efficient approach, termed sequence tagged fragments display, be developed that allow for the identification of genes from differential expression tissues, and analysis of genes involved in cytogenesis and pathogenesis.

基因表达调控决定于基因序列，如启动子、非翻译RNA区、蛋白质的结构域等，系统生物学包括组学、计算与合成生物技术，序列标志片段显示，可用于细胞系分化、病理变化等基因表达语、信号传导网络的系统分析与功能基因克隆。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
