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

同样的，手是手性的，分子也可以是手性的。

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

手性分子有一个原子——典型的碳原子——有四个不同的组吸附原子上。

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是右撇子或左撇子。

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

这是因为手性分子的不同变体——即对映体——是由所有相同部分组成，但是却以不同形式排列。

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，由三个碳原子和氮原子的连接环以及一些氧和氢组成，也被称为手性分子。

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

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