terminal bond 中文意思是什麼
terminal bond
解釋
端鍵-
First, a terminal double bond was introduced into 3 - amino - 9 - ethylcarbazole ( aec ) via methacryloyl chloride to obtain the compound, 3 - ( n - methacryloyl ) amino - 9 - ethylcarbazole ( mec ). second, mec was copolymerized with butyl methacrylate to prepare the mec - immobilized polymer particles. the resultant polymer particles were used as a fluorescence probe, which was almost free of dye leaching, and had higher photostability in comparison with free aec
首先利用甲基丙烯酰氯向3 -氨基- 9 -乙基咔唑（ aec ）分子中引入末端雙鍵，得到帶末端雙鍵的熒光指示劑3 - （ n -甲基丙烯酰基）氨基- 9 -乙基咔唑（ mec ） ，然後通過乳液聚合技術將mec共價固定到聚甲基丙烯酸丁酯基體上，制得一種共價固定了mec的聚合物顆粒。 -
The extracellular 100pl ( ecl1 ) and ecl2 was linked by disulfide bond to maintenanced the stability of the protein secondary structure. in recent years, we showed that ccr5 as a co - receptor could interact with hiv - 1 infect ion. ccr5 was paid closed attention to since it was cloned in 1996. the aim is to - obtain the sequence of first extracillular domain of 3 chemokine receptor 5 ( ccr5 ) n - terminal gene fragment with high level expression in e. coli and to prepare its specific antibody f ( ab ' ) ;, and its detected method
Ccr5具有g蛋白偶聯受體家族（ g - proteincoupledreceptors ， gpcrs ）所特有的7個跨膜區（ transmembrinedomains ， tm ） ，呈螺旋， tm的氨基酸有很高的保守性，膜外第一襻（ extracellularloop1 ， ecl1 ）和ecl2之間有二硫鍵相連，以維持蛋白質二級結構的穩定性。 -
In this thesis, several new fluorescence carriers have been synthesized bearing a carbon chain with a terminal double bond introduced into the molecule and copolymerized with a monomer under uv irradiation on the silanized glass or quartz disk. the sensors prepared were studied. covalent immobilization effectively prevents the leakage of the carrier dye from the sensor membrane, a phenomenon that shortens the lifetime of ordinary optical sensors
本論文合成了幾種含末端雙鍵、可共價固定的新型熒光化合物，並以此作為熒光指示劑，與膜基質單體在光引發劑作用下發生光聚反應共聚在經過硅烷化處理的石英或普通玻片上製成光極膜，制備了對一些物質有響應的熒光化學傳感器。
