The result was acetylsalicylic acid, the modern active ingredient in aspirin.

结果就乙酸，阿司匹林的现代活性成。

So, the active ingredient in aspirin is a compound called acetylsalicylic acid.

阿司匹林的活性成种叫做乙酸的化合物。

Soon, aspirin became synonymous with acetylsalicylic acid.

很快，阿司匹林就成了乙酸的代名词。

In 1853, a French chemist managed to chemically synthesize the compound, creating a substance called acetylsalicylic acid.

1853 年， 位法国化学家成功地化学合成了这种化合物，产生了种叫做乙酸的物质。

Now if you swap the methyls out for a couple of other slightly more complicated groups, then you get acetylsalicylic acid, or aspirin.

现在， 如果将甲基换成其他几个稍微复杂些的基团，就会得到乙酸或阿司匹林。

And thus, we can build the compounds we need, whether it be the simple stuff, like acetylsalicylic acid, aspirin, or something more complicated, like alpha-(5,6-dimethylbenzimidazolyl)cobamidcyanide, better known as vitamin B12.

因此，我们可以构建我们需要的化合物， 无论简单的东西， 如乙酸、阿司匹林，还更复杂的东西， 如 α-(5, 6-二甲基苯并咪唑基)cobamidcyanide， 也就众所周知的维生素 B12。
