这表明细菌的化学合成并不是这些生物的充足营养来源。
This suggests that bacterial chemosynthesis is not a sufficient source of nutrition for these creatures.
还必须认识到,许多重要的新生物产品仍将从现有生物分子衍生的模型化学合成。
It must also be appreciated that many important new bio-products will still be synthesized chemically from models derived from existing biological molecules.
而细菌呢,有点像通过化学合成的方式来为管虫提供食物,记得之前讲过的化学作用吧。
The bacteria, well the bacteria kind of feed the tubeworms through chemosynthesis, remember, that chemical reaction I described earlier.
These are things that must be taken in from the environment because your body cannot manufacture them and they promote specific chemical reactions in the body.
这些都是必须从外界摄取的物质,因为无法通过自身合成,它们能促进体内特定的化学反应
Because... you have to make these like, synthesized chemicals.
因为,你必须制作这些合成化学品。
So if you're trying to make a more complicated organic molecule carbon-carbon bonds are one of the most difficult things to make in organic chemistry, and it turns out that c n minus is a very reactive molecule, so it's a good way, even though we'll go over some drawbacks in a second, it is a good way to make carbon-carbon bonds.
如果你要合成一个更复杂的有机分子,碳碳键是有机化学中,最难制造的键之一,而实际上氰离子是一种具有很高活性的分子,用它是一个好办法,尽管我们一会儿将看到它的一些缺点,但它的确是一个制造碳碳键的好方法。
