LAMELLAR MODELS

  1. According to James Danielly & Hugh Davson (1935) cell membrane consists of 4 layers P-L-L-P.
  2. Molecules of phospholipid has amphipathic nature, i.e. it has polar & non-polar ends.
  3. Polar end is head consists of glycerol, which is attached to protein layer by Hydrogen & Ionic bonds (strongest bond) or Electrostatic forces.
  4. Non-polar end is tails consists of fatty acids, which are attached to each other by Vander wall forces (weakest bond) or Hydrophobic or Lipophilic interactions.
  5. Outer & inner surfaces of membrane consists of globular hydrated a-protein.
