Q5. Micelles and other lipid structures are incredibly important in biomaterial development and have even been seen in. ( 15 points total). a. What are the molecules that make up micelles and vesicles? Draw their structure and describe their unique properties. What is the driving force behind micelle \& vesicle formation? (5 points) b. Draw a plot of surface tension as a function of concentration and note what is happening at each stage of the graph. ( 2 points) c. Draw a plot of temperature as a function of concentration and describe the phases and important points. ( 2 points) d. Depending on the shape and size of the individual molecules, different supramolecular structures can form. Using the packing parameter, P=alV where V is the volume of the tail, l is the tail length, and a is the area per molecule at the interface, derive the ranges a packing parameter can take for ( 6 points, 2 each) i.
