Since the concentration of the two reactants start equal and remain equal throughout the reaction, the reaction can be treated as a simple second order reaction. I/[A]=kt+1/[A0]=1.0×10-2L·mol-1·s-1(100s)+1L/0. 100mol =11L/mol [A]=0.091M反馈...
狄尔斯-阿尔德反应（D-A reaction，简称“D-A反应”）是一类能够直接形成C-C键的重要有机反应，可以高效地实现对杂环、手性螺环和桥环等复杂结构的构建，也被广泛应用在天然产物和药物分子的合成中。吡咯吲哚霉素（pyrroindomycin，PYR）的生物合成途径中涉及两个D-A环加成酶PyrE3和PyrI4（图1）。这两个酶的...
为研究磷脂酰肌醇3-激酶(phosphoinositide 3-kinase,PI3K)/蛋白激酶B(protein kinase B,AKT)信号转导通路与CHKA的相互作用,另设DMSO组和LY294002组。采用实时荧光定量聚合酶链反应(real-time fluorescence quantitative polymerase chain react...
这是我的 《A Level 化学易错题系列》的第 8讲。 A level 有不同的考试局,比如CIE, Edexcel, AQA和OCR,咱们国内主要是前三个考试局。其实也只有前三个考试局才在非英国本土开放,其中以CIE和Edexcel考试局为主。 虽然都是英国的考试局,但是不同考试局的大纲内容并不完全一样,要么内容有些许差异要么同样的...
