Lipids are amphiphilic molecules that love and hate water simultaneously and self-assemble into a lipid bilayer that is a universal structure of all cell membranes. The membrane’s hydrophobic interior is a 3nm-thick film that separates the interior of the cells from the surrounding environment. Structures inside the cell, such as the nucleus, evolved to be bounded by membranes in eukaryote cells; in fact, it is the hallmark that sets them apart from prokaryotic cells.
