The compositions of the inner and outer surfaces of the lipid bilayer are different. Why do these differences exist and how might they be of use to a living cell?
In general terms, what would you expect to be different about the permeability of a lipid bilayer made of phospholipids (modern cells) and a bilayer made of fatty acids (protocell)?
Lipid bilayers formed between two aqueous phases have this important property: they form two-dimensional sheets, the edges of which close upon each other and undergo self-sealing to form vesicles (liposomes).
What properties of lipids are responsible for this property of bilayers? Explain
What is the significance of this property regarding the structure of biological membranes?
