The device scans employees' hands for contamination each time they wash and can detect gut biomolecules in just seconds.

该设备工每次洗手时扫描其双手否受到污染，并能几秒钟内检测出肠道生物分子。

Exactly how this happened is not known, but it involves biomolecules, molecules like DNA which are found in living things.

这到底如何发生的尚不清楚，但它涉及生物分子，像生物体内发现的DNA这样的分子。

As a result, the biomolecules were able to keep their natural shape.

结果，生物分子能够保持其自然形状。

And so a lot of these biomolecules are polymers.

很多生物分子都聚合物。

We're talking about uncovering entirely new biomolecules.

我们正谈论发现全新的生物分子。

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

这些分子以反应并启动一种反应链，最终产生类似生物分子的东西。

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

唾液中的各种生物分子吸收相同波长的光，但每一种都有不同的化学指纹。

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

所以一种生物分子能会色。另一种生物分子能会红色。

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

但似乎处于以产生生物分子的化学网络中心的有机分子氰化氢。

They're part of bigger molecular machines with these proteins interacting with other proteins as well as other biomolecules like DNA, RNA and small molecules.

它们更大分子机器的一部分，这些蛋白质不仅与其他蛋白质相互作用，还与其他生物分子如DNA、RNA和小分子相互作用。

We developed a new version of AlphaFold, called AlphaFold 3, that can model the structure of almost all biomolecules coming together with unprecedented accuracy.

我们开发了一个新的阿尔法折叠版本，称为阿尔法折叠3， 它以以前所未有的精度建模几乎所有生物分子的结构。

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.

冰不生物分子，但当它与碳混合时，冰分子中的原子会发生化，产生复杂的分子，——然后有趣的事情就开始发生了。

Closely related to genetics is molecular biology, which studies the molecular basis of biological activity, such as the structure and function of biomolecules like nucleic acids and proteins.

与遗传学密切相关的还有分子生物学，它研究生物活动的分子基础，比如核酸和蛋白质等生物大分子的结构和功能。

If more investigation is warranted, laboratory tests give valuable information by analysing blood, urine and other bodily fluids to measure levels of important biomolecules or detect the presence of disease or infection.

若需进一步调查， 实验室检测通过分析血液、尿液及其他体液， 提供宝贵信息，用以测量重要生物分子的水平或检测疾病和感染的存。

So proteins carry their function. But these proteins, they don't actually act in isolation. They're part of bigger molecular machines with these proteins interacting with other proteins as well as other biomolecules like DNA, RNA and small molecules.

所以蛋白质携带其功能。但这些蛋白质并不孤立作用的。它们更大分子机器的一部分，这些蛋白质会与其他蛋白质以及DNA、RNA和小分子等其他生物分子相互作用。
