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. (15[1])Bulky residues with this property such as tryptophan and (-5[1])phenylalanine (-5[1])are hidden inside proteins due to an “effect” named for this property. The (*) interior portion (10[1])of the cell membrane possesses this (-5[1])property, (10[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[2])
