A lot of the examples that we're going to give you in terms of trying out your Lewis structures will be molecule that are used in organic synthesis, or maybe they're molecules that react in interesting ways with biomolecules in your body or proteins in your body.
很多我们将要用来,训练路易斯结构的例子,都是在有机合成中用到的分子，也有可能是那些在你体内的生物分子,或者蛋白质中发生有趣反应的分子。
-
Steroids are small molecules - much smaller than proteins - smaller molecules that tend to be hydrophobic or lipid soluble.
类固醇是小分子物质,比蛋白质小得多,这类小分子是非水溶性的,或者说是脂溶性的
-
Plaques are unusual clusters, or groups,of proteins.

Because of this, they can't repair the various kinds of damage they need, or create the amino acids and proteins they need.
他们不能修复各种损伤,或者生成所需的氨基酸蛋白质
-
I couldn't have told you, for example, if we look at a phosphate group, that that's going to be incredibly important in DNA, that it's also an incredibly important group when you're dealing with proteins and whether you're turning the function of a protein on or off.
怎么和化学反应相联系起来的，更不记得其它我更不感兴趣的规律,我不能告诉你，如果我们看磷酸盐,它们对于构成DNA十分重要,也是构成蛋白质的重要组份,它是否能打开或关闭一个蛋白质的功能。
-
Now, you know already, or you could review in Chapter 4 that I provided to you, something about how proteins work.
现在你们已经知道,或者读我给你们看的第四章,就能了解蛋白质的工作原理
-
Hormones can be proteins, endocrine hormones can be proteins, meaning they're large molecules that are usually fairly water soluble, or they can be steroids.
激素可以是蛋白,内分泌激素可以是蛋白,这意味着激素是大分子,并且通常是水溶性的,激素也可以是类固醇
-
That's what makes proteins useful in transmitting or responding to signals.
它们能够传导信号,或者反馈信号
-
The other way that they define - or find stem cells is that over the years of studying them we've begun to recognize some of the proteins, the specific proteins that are produced by these characteristic cells.
而另外一种能让研究人员定位,或者找到干细胞的方法就是,多年研究后,我们开始能识别一些蛋白,这些特定的蛋白是由,这种特殊的细胞生成的
-
Out of all the genes that are on the human genome which fraction is this particular cell using, which fraction is it expressing determines what proteins are present in the cell, determines what work or what activities the cell can engage in.
人类基因组全部基因中的,特定细胞所表达的基因片段,细胞表达的是哪段基因,决定了细胞中存在什么样的蛋白,决定了细胞会有什么样的功能,或者参与何种生命活动
-
We're going to talk a lot about antibodies over the next week or so, but antibodies are specialized proteins that, as you know, are designed to bind to antigens or foreign molecules inside the body.
我们将会在接下来的几周,讲许多关于抗体的内容,抗体是一种特殊蛋白质,众所周知,抗体用于结合身体内的抗原和外源分子
-
Antibodies look like this, they're big proteins, if you looked at them under a microscope or if you looked at them in cartoons they're shaped like the letter Y.
抗体看起来就像这样,它们是大型蛋白,如果你用显微镜观察抗体,或者从图上看的话,它们都呈字母Y形
-
The other thing that it does is that when a virus is inside these cells making its proteins, some of those proteins get processed or digested into small fragments that are themselves antigens.
HC的另一项作用是,当病毒在细胞内表达蛋白时,一些蛋白被加工,或者,分解成小片段而成为抗原
