But if we change the shape of a constrained peptide by too much, those extra chemical bonds are unable to form and the whole molecule falls apart.

是如果我们过度改变限制性肽的形状，那些额外的化学键便无法形成，整个分子结构也会随之瓦解。

These are of two varieties, known as single and double bonds.

化学键有两种，单键和双键。

Photosynthesis takes sunlight and stores solar energy in chemical bonds.

的光作用吸收了太阳能并把存储化学键中。

In part, these PFAS are effective because their chemical bonds are incredibly strong.

某种程度上，这些 PFAS 有效的原因是因为们的化学键非常牢固。

It's a chemistry that allows two molecules to come together and form a bond even when they're surrounded by all the stuff that you would find in human cells and even in the human body.

是一种能够生物体中进行、让两个分子结并形成化学键的化学物质。

But while researchers have tried optimizing those temporary bonds for those properties, the researchers behind this study wondered what would happen if the temporary bonds actually stuck around a little longer.

是，尽管研究人员已经试图优化这些暂时性化学键的属性，这项研究背后的研究人员想知道如果暂时性化学键实际停留的时间稍长一点会发生什么。

So the bacteria use an enzyme called glucosyltransferase to cut the bond between them, use the fructose for energy, and add the glucose to a growing chain of glucose molecules called a glucan.

细菌会通过葡萄糖基转移酶分解们之间的化学键，然后利用果糖供能，并把葡萄糖连接到一种叫作葡聚糖的延伸的糖链上。

And eventually, it grows so strong that it pulls apart matter itself, breaks bonds, pulls apart atoms, and reduces everything to fundamental particles and that's the end of the universe.

最后变得非常强大以至于把物质本身分开，打破化学键，把原子分开，把所有东西都分解成基本粒子，这就是宇宙的终结。

A rocket is basically a way to take the energy stored inside chemical bonds and use it to crawl out from the bottom of our gravity well.

火箭基本上是一种获取储存化学键中的能量并使用从我们的重力井底部爬出来的方法。

Hysteresis loss, as this is known, can be reduced by mixing a tyre's rubber with powdered material that has strong chemical bonds in it.

轮胎的橡胶中混具有强化学键的粉末材料可以降低这种称之为“滞后损耗”的现象。

And that's the way that the bonds, when they freeze, they actually force the water to have a fixed side.

这就是化学键，当们冻结时，们迫使水有固定的一面。

Spotting more complex substances was almost impossible because their rotational energy is scattered by their numerous bonds across a wide range of frequencies.

而鉴别更复杂的物质几乎不可能，大量化学键占有很宽的频率范围，以至于旋转能被散射掉。

Right – because gum actually creates a chemical bond – which means when one thing joins firmly to another.

对，因为口香糖实际上会和其他与之接触的物体之间产生化学键，两者会很紧密地粘连起来。

Well, in nature, most things decompose because bacteria breaks down the chemical bonds that hold a substance together.

自然界中，大多数物质都会分解，因为细菌会破坏将物质结一起的化学键。

Finally, DNA polymerase fills the gaps on both sides of the union and DNA ligase seals the bond.

最后，DNA聚酶会填补两侧连接处的空白；DNA连接酶会将化学键连接起来。

And one of the keys to breaking these bonds is through oxidation.

破坏这些化学键的关键之一是通过氧化。

They've got extra chemical bonds that constrain the shape of the molecule, and this makes them incredibly stable as well as highly potent.

们拥有额外的化学键来约束分子结构，因此们异常稳定，效力强大。

Fibers have molecular bonds that are resistant to human intestinal enzymes, so they pass through the small intestine undigested, get broken down a bit by bacteria in the large intestine, and ultimately end up as bulk matter in the stool.

纤维素各分子间的化学键无法被人体的消化酶水解，所以们经过小肠而不会被消化吸收，只是大肠内肠道菌的作用下被少量分解，最终成为团块状，同粪便排出体外。

The hypothesis was that longer-lasting bonds would nudge the SPN towards a state that is more resistant to any forces applied to it.

他们假设持续时间更长的化学键会促使SPN对施加其上的任何作用力都更具有抵抗力。
