Concept 1: Membrane Structure

Membranes consist of a phospholipid bilayer combined with a variety of proteins in a fluid mosaic arrangement.

The surfaces of cell membranes are hydrophilic (water-loving); the interiors are hydrophobic.

Hydrophilic molecules tend to interact with water and with each other. Hydrophobic molecules avoid interaction with water and tend to interact with other hydrophobic molecules.
