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 phenylalanine are hidden inside proteins (15[1])due to an “effect” named for this property. The (*) interior portion of the cell membrane (-5[1])possesses this property, as it largely consists of hydrocarbon chains. (10[1])Molecules with this property will separate from an aqueous solution. For 10 points, name this “water-fearing” (10[1])property of some molecules, unlike hydrophilicity. ■END■
