Catabolism metabolic reactions involved in the breakdown of complex molecules to simpler compounds as , for example , inrespiration 分解代谢:这种代谢反应主要是把复杂的分子分解为简单的化合物,例如呼吸作用。
A complex molecule and snake enom may proide researchers with a more reliable method of diagnosing human diseases and deeloping new drugs 一种新合成的分子和蛇的毒液将给研究人员提供用于诊断疾病和开发新药的可行性方法。
Researchers had previously thought that carbon dioxide ? which is not present in titan ' s atmosphere ? would stifle the reactions that produce complex molecules 研究员们先前估计二氧化碳(泰坦星的大气中没有这个成分)会阻止化学反应生成复杂的分子。
In the process , they have devised noninvasive ways to deliver complex molecules , such as using ultrasound to blast drugs through the skin painlessly 在这个过程当中,他们利用非侵入式设计来投送复杂的分子,像是利用超音波以无痛的方式将药物轰进皮肤。
The young earth could have also received more complex molecules with enzymatic functions , molecules that were prebiotic but part of a system that was already well on its way to biology 年轻的地球也会接收到具有酵素机能的复杂分子,还有一些分子尚属于前生命期,却是准生命系统的一部份。
The major results are as follows : ( 1 ) complexing action is fundamental for this method , while the interaction of molecules in gel precursor is important for uniformity . the ideal structure of complex gel is that complex molecules in the gel connecting with each other mainly by chemical bonds 得出以下结论: ( 1 )络合作用是络合物溶胶凝胶法的基础,凝胶中分子间的作用方式是影响凝胶中组分均匀性的重要方面,理想的络合物凝胶结构应该是络合物分子之间更多的以化学键合的形式相联。
