BIS 104 PQ 7a ans 08 7. The lipid composition of biomembranes has a strong influence on the physical and physiological properties of membranes such as the plasma membrane of the cell. Among the membrane lipids, phospholipid play a major role in determining these properties. Briefly describe how each of the following lipid properties influence the nature of the plasma membrane: a) Phospholipids are amphipathic. A molecule that amphipathic has both hydrophilic and hydrophobic regions, thus giving

Unformatted text preview: it a dual nature. The amphipathic phospholipids will arrange themselves in an aqueous solvent so that the hydrophilic head groups will maximize their exposure to the solvent, while the hydrophobic fatty acid tails will group together internally to minimize exposure to the solvent . Therefore, a lipid bilayer membrane will always seal itself into a closed vesicle so that there are no free edges....
