So, we have a transfer of the chiral information from the catalyst to the products.

手性信息从催化剂转移到了产物上。

In thalidomide, for example, the chiral center is a carbon atom attached to one of the rings.

例如在萨力多胺中，手性中心一吸附在一环上的碳原子。

A chiral molecule has an atom—typically carbon—with four different groups attached to it.

手性分子有一原子——典型的碳原子——有四不同的组吸附原子上。

An asymmetric organocatalysis that means that the catalyst, our small well-defined organic catalyst is asymmetric, that it's chiral.

不对称有机催化也就说，们的小而明确的有机催化剂不对称的，手性的。

And in the same way, as our hands are chiral, molecules can be chiral.

同样的，手手性的，分子也可以手性的。

If you position the version of the molecule that's considered " right-handed" , called the R enantiomer, so the closest oxygen atom to the chiral center is below it, the hydrogen atom attached to the center will be facing away from you.

如果你找到了“右撇子”的分子变体，即R对映体，那么离手性中心最近的氧原子就在它的下方，附在中心的氢原子将背朝你。

Thalidomide, which is made up of three connected rings of carbon and nitrogen atoms, plus some oxygen and hydrogen, is what's known as a chiral molecule.

萨力多胺，由三碳原子和氮原子的连接环以及一些氧和氢组成，也被称手性分子。

So, our hands are mirror images of each other, they are chiral because we cannot put one on top of the other and make them look identical.

们的手彼此的镜像，它们手性的，它们并不完全重合。

Chiral comes from the Greek for hand or claw, and chemists often think of chiral molecules as being right-handed or left-handed.

手性一词来源于希腊指手或爪，化学家们通常将手性分子当成右撇子或左撇子。

And that's because the different versions of chiral molecules—called enantiomers —are made up of all the same parts, but arranged differently.

这因手性分子的不同变体——即对映体——由所有相同部分组成，但却以不同形式排列。

These groups are kind of like your fingers: in each enantiomer, the groups are attached to the chiral center in the opposite order, so they’re mirror images of each other.

这些基团有点像你的手指： 在每对映异体中，这些基团以相反的顺序附着在手性中心， 所以它们彼此的镜像。

In two, but molecules can have more than one chiral center, and that's not the only stereosometry that they can have.

在二维中， 但分子可以拥有不止一手性中心，这并非它们唯一的立体化学性质。

So the point of this sort of chiral transition that I'm putting out is chirality is actually a signature of being in a complex chemical space.

因此，提出的这种手性转变的核心在于，手性实际上存在于复杂化学空间中的一标志。

And that’s because the different versions of chiral molecules — called enantiomers — are made up of all the same parts, but arranged differently.

那因不同版本的手性分子— — 称对映体—— 由所有相同的部分组成， 但排列不同。

You push your molecules to a large enough complexity that chiral molecules become very likely to form.

你将分子复杂度提高到一定程度，手性分子就非常有可能形成。

And then there's a cascade of molecular recognition where chiral molecules can recognize each other.

于，分子识别过程如瀑布般层层递进，其中手性分子能够彼此识别。

But if you get to this threshold boundary, above that boundary, almost every single molecule is chiral.

但一旦跨越这一阈值边界，在边界之上，几乎所有分子都具有手性。

People take for granted the existence of chiral molecules at all, that this property of having a handedness, and they just assume that it's just a generic feature of chemistry.

人们理所当然地手性分子存在的，这种具有手性的特性，他们只假设这化学的一普遍特征。
