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

同样的，手手性的，分也可以手性的。

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

手性分有一个——典型的碳——有四个不同的组吸附。

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产物。

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，我们的小而明确的有机催化剂不对称的，手性的。

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，手性中心一个吸附在一个结构环的碳。

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当成右撇或左撇。

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

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

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

那因为不同版本的手性分— — 称为对映体—— 由所有相同的部分组成， 但排列不同。

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.

我们的手彼此的镜像，它们手性的，它们并不完全重合。

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，由三个碳和氮的连接环以及一些氧和氢组成，也被称为手性分。

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： 在每个对映异构体中，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。

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.

如果你找到认为“右撇”的分变体，即R对映体，那么离手性中心最近的氧在它的下方，附在中心的氢将背朝你。
