参考答案：

hydrophilic：亲水的。一个原子团被水溶剂化的倾向。用英语解释为：(1)Pertaining to molecule or groups that readily associate with H₂O.(2)Pertaining to molecule that are solube in water. (指可溶性分子或基团表现出的易与水亲和的性质)

hydrophobic：疏水的。水介质中球状蛋白质的折叠总是倾向于把疏水基团埋藏在分子的内部，躲开与溶剂水的接触，这一现象是疏水相互作用。也就是说疏水的是指一个原子团抗水溶剂化的倾向。用英语解释为：

(1)Literaly, water-hater, used to describe molecules or founctional groups in molecules that are, at best, only poorly Soluble in water.

(2)Pertaining to molecule that do not mix with water. (用来描述只能微溶于水的分子或分子中某些功能团所表现出的与水互不相溶的性质。)
