这就得到脱氧的苯衍生物(105)。
结果表明:微孔阴极中的颗粒连通性好、颗粒尺寸小以及孔隙率高都有利于电脱氧的进行。
The results show that small particle size, good connectivity among particles and high porosity of the cathode enhance the rate of electro-deoxidation.
脱氧核糖核酸分子是由许多更小的分子组成的。
DNA also has this sort of combinatorial system where you have a finite number of, I guess, bases or amino acids that could combine to a possible infinity of strings of DNA strings.
脱氧核糖核酸也拥有这种组合系统,你的生物基础或氨基酸数量是有限的,但却能组合出,几乎无限的脱氧核糖核酸螺旋结构
This is important because this molecule here, deoxyribose, is not the same upside down as it is - it's not symmetrical upside down and right side up, it's different because the 5' carbon's either pointed up or pointed down.
这很重要,因为对脱氧核糖来说,不都是像这样自上而下的,不是对称的自上向下或全部向上的,长链不同是由于,5'碳向上或者向下的指向不同
Every unit in the backbone of this ladder has the same sugar unit, the same pentose; it's either RNA or DNA and has ribose or deoxyribose, so you don't need to describe the whole thing.
主链的每个单位,都由相同的糖单位构成,同样的戊糖,RNA里是核糖,DNA里是脱氧核糖,所以你不需要所有细节都描述
