Unit Membrane Model
Lamellar model was supported by Robertson. According to Robertson
All biomembrane have similar structure (like PM), on the basis of this observation put forward the concept of Unit membrane.
According to unit membrane concept - all biomembranes from prokaryotes to eukaryotes have similar trilamellar structure.
A unit membrane has a thickness of 75Å. (nuclear membrane thicker than 75Å) and made of 2 or more layer.
Each of 2 electron dense surface layers is 20Å thick, it is formed of extend or b-protein molecules.
Outer protein layer consists of mucoprotein. Inner protein layer consists of non-mucoprotein.
Central electron transparent layer is 35Å thick, which is c/o bimolecular layer of phospholipids.
Drawback of unit membrane model - This model also doesn't explain permeability & elasticity of PM.
