One thing that I want to mention that is really important is once you have double bonds, what happens between those two atoms in the molecule is they can no longer rotate in relation to each other.

我要提醒你们的非常重要的一点事,一旦有了双键，分子中的两个原子,就不能相对旋转了。

Well, one way to think about is they have more antigen binding sites and so they're going to be more efficient at neutralizing the pathogen on a per-molecule basis than IgG is.

可以这么考虑,因为IgM表面有更多的抗原结合位点,所以相对于IgG,IgM在分子层面上,能够更为有效地与病原体结合
