3. As discussed in class, single lipid layers are a great way to package materials (like drugs or vaccines) so that they can cross the lipid membrane and get into a cell. i) Discuss why most molecules can not cross the lipid bilayer. ii) Discuss why drugs, when packaged in a lipid membrane, can pass through the lipid bilayer. iii) Hypothesize how you would get materials into the lipid membranes shown below and why the thermodynamics of the system force the lipid membrane into spheres. iv. Would it be beneficial to add cholesterol to these layers to facilitate the transport of materials?
