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.
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。

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.
Oral absorption of hydrophobic drugs can be significantly improved using lipid-based non-particulate drug delivery systems, which avoid the dissolution step.
