WebBy aggregating together, nonpolar molecules reduce the surface area exposed to water and minimize their disruptive effect. The hydrophobic effect can be quantified by measuring the partition coefficients of non-polar molecules between water and non-polar solvents. WebRegion 1 is hydrophilic because it interacts with the interior of the membrane, whereas region 2 is hydrophobic because it interacts with an aqueous environment. B Region 1 is hydrophilic because it interacts with an aqueous environment, whereas region 2 is hydrophobic because it interacts with the interior of the membrane. C
