So, now you have a single molecule, very large molecule, with not just two binding sites but with ten binding sites.

所以如果你体内有一个细胞,一个体积很大的细胞,细胞表面不只有两个抗原结合位点,而有十个抗原结合位点

This is incredibly important because if you picture having a double bond in a very large molecule, you could have all sorts of other atoms off this way and all sorts of other atoms off this way, and you can picture the shape would be very different if you have one confirmation versus another confirmation.

这是十分重要的,因为如果你想象在一个大分子里有一个双键，你可以在这里有各种各样的其它原子,在这里也有各种各样的其它原子，你可以想象一个构型,和另外一个构型之间的形状差别是非常大的。

The big Pharma hasn't really done research for years but then he married in the biotech area and therefore biotech companies aren't that well run but they spent a great deal in research for the large molecule drugs.

大型制药企业已经很多年没有做过相关研究,但它却与生物技术领域合作,因此导致众多生物技术公司经业绩下降,但生物技术公司在大分子药物的研究上,却投入了很多。

And that's all that's big enough to pass through or small enough to pass through. And if we go up even just one row on the periodic table to potassium, what we actually see is now that it's going to be too large, and, in fact, a potassium solvated with one water molecule won't go through our channel.

就是这样刚好大到它通过,或者说刚好小到它通过,即使我们再沿着周期表往下走仅仅一行到钾离子，我们看到的就将是它的个头太大了，实际上，溶解于一个水分子的单个钾离子,不能穿过我们的通道。
