胆固醇也是大多数细胞膜脂质的组成成分,它有一个羟基基团,即一个微小的极性头部连接到一个刚性的疏水性的尾端。
Cholesterol is another lipid component of most cell membranes. It has a hydroxyl group, a tiny polar head group so to speak attached to a rigid hydrophobic tail.
FMN是紧密结合的蛋白质,辅酶Q具有疏水性尾部,使得它在线粒体膜的脂质双分子层的可溶性。
FMN is tightly bound to proteins while coenzyme Q has a hydrophobic tail that makes it soluble in the inner mitochondrial membrane's lipid bilayer.
双分子层中,脂质可以自行排布,形成极性头部暴露在水中,疏水尾部夹在中间的结构。
In a lipid bilayer, lipids arrange themselves, so that their polar head groups are exposed to water and their hydrophobic tails are sandwiched in the middle.
利用非微粒脂质给药系统,药物不必经过溶出的步骤,从而可以显著的提高疏水性药物的口服吸收。
Oral absorption of hydrophobic drugs can be significantly improved using lipid-based non-particulate drug delivery systems, which avoid the dissolution step.
