The head is hydrophilic, which means it easily attaches to water molecules.

头部是亲水性的，这就意味着它很容易附着在水分子上。

The hydrophilic sugar chains help mucin dissolve in your body's watery fluids.

水糖链帮助粘蛋白溶解於你身体内的液体。

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，另一面疏水——是所有表面活性剂的显著特征。

One end of the molecule is hydrophilic — it easily associates with water, the main ingredient in sweat.

分子的一端是亲水性的——它很容易与汗液的主要成分水联系在一起。

The hydrophilic ends dissolve in water so that whatever the other end sticks to can be rinsed away.

亲水性末端溶解在水中，这样另一端粘在上面的任何东西都可以被冲洗掉。

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.

胆汁酸和胆盐同时具有疏水性和亲水性，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。

A non-conservative substitution means that the new amino acid - valine, which is hydrophobic - has different properties than the one it replaced - glutamic acid, which is hydrophilic.

非保守性替换意味着新氨基酸，疏水性的缬氨酸，与其替代的氨基酸，亲水性的谷氨酸，有着不同特性。

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疏水的尾部，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。
