So, what happens, this is another view of a sodium channel, so this is actually looking a little bit more at the protein structure.
那么,这里发生了什么,这是钠离子通道的另一张图片,在这种蛋白质结构中,它看起来更复杂一点。
Sometimes subtle changes in the structure of a protein can convert it from an active state into an inactive state.
有时蛋白质结构上一些很小的变化,就能将其由激活态转变为非激活态
The reason it is so exciting that it's a protein, and it's a protein, this is the structure here, it's a ribbon structure so you can kind of see what it looks like, it's made up of all natural amino acids.
它这么让人激动的原因是因为它是一个蛋白质,这里的这个结构,这是个带状机构,你可以看到它的样子,它全部是由氨基酸组成的。
You know that the function of a protein is intimately related to its structure.
蛋白质的功能与结构密切相关
And if you've forgotten about proteins and what their structure is you can go to Chapter 4 and read sort of a brief review of protein biochemistry.
如果你们忘记了蛋白质及结构的相关知识,就去读第四章,关于蛋白质生物化学的简短综述
That - irreversible changes happen all the time too but here I'm talking about very subtle small changes where you're changing the structure of the protein but only a little bit such that it can go back.
这种不可逆的改变时时刻刻都在发生,但我在这里想讲的是,对蛋白质结构进行微小的改变,小到这种改变是可逆的
