How would vesicles be organ- ized if they formed in a nonpolar solution as opposed to in water? 2. You may have noticed that before you get an injection, your skin is wiped with an alcohol solution. Alcohol solutions are frequently used as degerming agents because they interfere with hydrogen bonding in proteins. Describe what effect disruption of hydrogen bonding may have on a protein's structure and function.
