螯合基團 的英文怎麼說
中文拼音 [áogějītuán]
螯合基團
英文
chelate group-
Both the frequency and intensity of 1146. 0cm - 1 change largely, etc. discussed and compared the mechanism of these interaction in detail we got some conclusions as following : both zn2 + and cd2 + ions can chelate with po2 - and come into being - po2 - me2 + n7 ( purine ) chelate. as to zn2 + ions, when r2. 0, the quantity of po2 - zn2 + n7 is directly linear with r. when r2. 0, zn2 + ions even can chelate with c at n3 - o2 sites and this chelation will disrupt the h - bond between gc base pairs and make the dna structure unstable. as to cd2 + ions, only when r is within 1. 0 - 1. 5 can this chelation take place and the relation of the quantity of this chelate with r is not easy to conclude
通過對這些變化進行詳細討論和分析，我們得到了如下的結論： zn ~ （ 2 + ）和cd ~ （ 2 + ）都可以跟dna的磷酸基團螯合，形成- po _ 2 ~ - … me ~ （ 2 + ） … n7 （ g ）螯合物，但是前者的螯合跟離子濃度有很大的關系，在摩爾濃度比小於2 . 0時，螯合物的生成量跟r成正比關系，而後者的螯合跟離子的關系不是很明顯，只有當r處於1 . 0至1 . 5之間時，螯合作用才能進行，並且螯合物的生成量跟r之間沒有很明顯的關系存在。
