Biomembranes I:
Membrane Structure and Transport
Concept 1: Membrane Structure
Membranes consist of a
phospholipids 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.
