Round 8: Tossup 14

Regions with high values of this property will appear as spikes in the “score value” on a Kyte-Doolittle chart. Removal of molecules with this property during protein folding reduces clathrate-like formations, increasing entropy. Bulky residues with this property such as tryptophan and (15[1]-5[1])phenylalanine are hidden inside proteins due to an “effect” (15[1])named for this property. The (*) interior portion of the cell membrane possesses this property, (-5[1])as it largely consists of hydrocarbon chains. Molecules with this property will separate from an aqueous solution. For 10 points, name this “water-fearing” property of some molecules, unlike hydrophilicity. ■END■ (10[1])
