  • So, then we go to thermodynamics and chemical equilibrium, and this is really about chemical reactions -- weather a reaction will go, will it be spontaneous, if there an equilibrium, what direction will the reaction be shifted in.

    然后我们要讲到热力学和化学平衡,这都和化学反应有关,一个反应是否能发生,是不是能自发反应,如果存在化学平衡,它会朝什么方向移动。

  • Generally, there are a couple of elements that one might set down as in a Petri dish, and wait to see if some chemical reaction might take place, but not at all sure of what it might be.

    一般来说,都有几个元素,作者会把它们像放入培养基中一样培养,等待某种化学反应的产生,但对可能的结果却一无所知。

  • So, a protein that has tyrosine and it has tyrosine in a position such that it's on the outside of the protein and accessible to chemical reaction can be phosphorylated.

    所以,一种蛋白质中含有酪氨酸,并且该酪氨酸位于,像蛋白质的外侧这样的位置,这样才能够发生磷酸化反应

  • Some proteins can be switched from an 'off' position where they don't do anything to an 'on' position where they now do something by only a chemical reaction like this where a phosphorous is added.

    一些蛋白质可以从关闭状态的,无所作为,到成为开启状态后,执行某种功能,中间只发生了一个引入磷酸基的化学反应

    耶鲁公开课 - 生物医学工程探索课程节选

  • It performs a chemical reaction on the protein, taking a phosphorous from ATP and moving that phosphorous onto the protein.

    它能够催化蛋白参与如下反应,即将ATP上的一个磷酸基团,转移到蛋白质上

  • It's not a chemical reaction.

    它不是化学反应。

    麻省理工公开课 - 热力学与动力学课程节选

  • Restriction enzymes are just a kind of enzyme, enzymes are protein molecules that make a chemical reaction go faster, and the chemical reaction that restriction enzymes do is cutting DNA.

    限制性内切酶是一种酶,而酶是加速化学反应的蛋白质分子,限制性内切酶加速的化学反应,是切割DNA
