They're naturally hydrophobic, meaning they won't absorb water.

它们天生水性，意思是它们不会吸收水分。

I coated this glass with a hydrophobic coating that does just that.

我用给这个玻璃加了有那个功能的水涂层。

Water molecules also repel the hydrophobic ends of surfactant molecules.

水分子也排斥表面活性剂分子的水端。

This makes the hydrophobic effect disappear, and gives the molecules room to move around.

这会让水效应消失，并提供了让分子移动的空间。

The molecules' hydrophobic ends are attracted to fat and dirt, which they quickly surround.

分子的水性末端被脂肪和污垢所吸引，它们会迅速包围油脂污垢。

Their shared reaction to water makes the lipids stick loosely together—this is called the hydrophobic effect.

头尾对水的反应让脂质分子松散地附着在一起，这是水效应。

This two-sided property — one side hydrophilic, the other hydrophobic — is a distinguishing feature of all surfactants.

这种双面性质——一面亲水，另一面水——是所有表面活性剂的显著特征。

The other end is hydrophobic — it readily associates with the oily surface of the horse's coat.

另一端是水的——它很容易与马皮毛的油性表面联系在一起。

The tail is hydrophobic, which means it repels water and instead attaches itself to oils or fats.

尾巴是水的，这意味着它可以排斥水分子，而是附着在油脂上。

Experts suspect the surfaces may be covered with some kind of hydrophobic material that repels water molecules.

专家揣测其表面可能覆盖有排斥水分子的水材料。

When you surround a coronavirus with water, the hydrophobic effect gives the bonds within the membrane their strength.

当你用水裹住新冠病毒时，它的水效应会让膜内结构更坚不可摧。

The fats in your pastry dough are hydrophobic, meaning the butter and oil molecules don't like binding with water.

酥皮面团中的脂肪有水性，这意味着黄油和油分子不易与水结。

Here's what they saw. The leaves are extremely hydrophobic, meaning water beads up to minimize contact with the surface.

以下是他们观察到的情况。叶片极其水，这意味着上面的水会形成水珠，尽量减少与叶面的接触。

(gentle music) the water anole is a semi-aquatic species with hydrophobic skin that repels water.

（轻音乐）水变色龙是一种半水生物种，有水性皮肤，可以排斥水。

But if that hydrophobic region helps human insulin bind to our cell receptors, how would this insulin manage it?

但是， 如果那个水区域帮助人类胰岛素与我们的细胞受体结，那么这种胰岛素将如何管理它呢？

Here's what they saw: the leaves are extremely hydrophobic—meaning water beads up to minimize contact with the surface.

这是他们所看到的：叶子有极强的水性——这意味着水珠会聚起来，以尽量减少与表面的接触。

Put those things together, that can help you live to 100. Well, if you're acrophobic or hydrophobic, this pool ain't for you.

把这些东西放在一起， 可以帮助你活到 100 岁。好吧，如果你有恐高症或水症， 这个游泳池不适你。

These acids and their salts have both hydrophobic and hydrophilic sides, making them amphiphilic, which help them make cholesterol and fat in the gut more soluble in bile.

胆汁酸和胆盐同时有水性和亲水性，即两亲性，得益于此，胆汁可以更好地溶解肠道中的胆固醇和脂肪。

And it turns out that microscopically rough surfaces tend to be more hydrophobic, because they can trap pockets of air and minimize the interaction between water droplets and the surface of the material.

结果显示，显微镜下，粗糙的表面拥有更好的水性，因为它们可以捕捉气囊，最小化水滴和物质表面的相互作用。

These surfactants have their hydrophilic head and their hydrophobic tails, and so they form these micelles around the dirt, which is what grabs onto dirt and oil, and helps it to remove it from the hair and the scalp.

这些表面活性剂有亲水的头部和水的尾部，所以它们在污垢周围形成胶束，这些胶束可以吸附污垢和油脂，并帮助它们从头发和头皮上清除。
