For 10 points, name this property possessed by oils, fats, and other substances that repel water.
Two measures of this property are the logs of the distribution coefficient and the partition coefficient. Those are the "log D" and "log P" measures, respectively. Substances with this property have very high contact angles, which may cause them to exhibit the lotus effect. An interaction named for this property contributes to the stability of protein tertiary structure, as amino acids with this property are entropically favored to clump together. The fatty tails of phospholipids have this property, which is why they are found buried within double membranes. For 10 points, name this property possessed by oils, fats, and other substances that repel water.
Two measures of this property are the logs of the distribution coefficient and the partition coefficient.
hydrophobicity [Accept lipophilicity. Accept hydrophilicity before "contact angles."]
