I just wanted to point out that although you see these chlorine atoms in these drugs, in fact, I don't think I've ever seen an acid chloride in a final pharmaceutical product or drug that we take, and the reason is because they're so reactive that you wouldn't want to have that in something you digest.

我只是想指出一点,那就是尽管你在这些药物中看到了氯原子，实际上，我想我从来都没有在一个,成品的药用产品或者药物中见到过酰氯，这原因是因为它们太容易反应了,你不会想让它们出现在你要消化的东西中。
