WebPhosholipid Structure. Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer. Web20 feb. 2014 · In the scientific community, we have come to accept the definition that a surface is hydrophobic when its static water contact angle θ is >90° and is hydrophilic when θ is <90°. There is actually very little rationalization as why the surface switches from being hydrophilic to hydrophobic when θ changes only 2° from 89 to 91°.
