One end of the molecule is attracted to water, the other end to fat.

分子的一端，另一端脂肪。

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

头部是的，就意味着它很容易附着在分子上。

Their new material is a type of hydrogel, a material made from a network of molecules that hold onto water.

它们的新型材料是一种，是一种由极为的分子网络所构成的材料。

They're hydrophobic or hydrophilic, basic or acidic.

它们是疏的或的、碱的或酸的。

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.

非保守替换意味着新氨基酸，疏的缬氨酸，与其替代的氨基酸，的谷氨酸，有着不同特。

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.

些表面活剂有的头部和疏的尾部，所以它们在污垢周围形成束，些束可以吸附污垢和油脂，并帮助它们从头发和头皮上清除。

Previous work had shown that titanium dioxide could be rendered superhydrophilic (intensely attractive to water) upon exposure to ultraviolet light—a hindrance under extremely foggy conditions, as water would stick to the mesh rather than trickle into the cistern.

之前的研究表明， 二氧化钛在暴露于紫外线后会变得超（对有强烈的吸引力）——在极度多雾的条件下会造成阻碍，因为会粘附在网上而不是滴入箱。
