4.So one kind of biomolecule might get a blue color. Another kind of biomolecule might get a red color.

所以一种生物可能会变成蓝色。另一种生物可能会变成红色。机翻

5.Various biomolecules in saliva absorb light at the same wavelength— but each has a distinct chemical fingerprint.

唾液中各种生物吸收相同波长光，但每一种都有同化学指纹。机翻

6.And these molecules could react and start a sort of a reaction chain that would eventually lead to something like a biomolecule.

这些可以反应并启动一种反应链，最终产生类似生物东西。

7.But the organic molecule that seems to be at the center of the chemical networks that can produce biomolecules is hydrogen cyanide.

但似乎处于可以产生生物化学网络中心有机是氰化氢。机翻

8.Ice is not a biomolecule, but when it mixes with carbon, the atoms in ice molecules change to produce complex molecules – and that's when interesting things start to happen.

冰是生物，但当它与碳混合时，冰中原会发生变化，产生复杂，——然后有趣事情就开始发生了。
