- The components are free to move with respect to each other and the proteins embedded in the bilayer vary in shape, size and pattern.
- Phospholipids /lipid bilayer
- Barrier -separates contents from outside
- Phospholipids allow fat soluble substances through.
- Hydrophilic/ hydrophobic tails/heads
- Hydrophilic channels
- Glyco-protein/ glyco-lipid
- Cholesterol effects fluidity
- Carrier proteins allow proteins through (selective) -facilitated diffusion
- Used for active transport
