Hydrophobic moment 是什么

疏水效应(英語:Hydrophobic effect)又稱疏水性效應,屬於非極性分子的一種性質,會使這些分子在水溶液中具有自我聚集(self-associate)的特性。例如油在水中會呈現與水分離的現象。 此外這種現象對於蛋白質的型態、不同蛋白質之間的交互作用,以及核酸結構等生化分子也有所影響。例如某些擁有疏水核心(hydrophobic core)的蛋白質,會以疏水軸為中心形成捲曲螺旋(coiled-coil)結構。在水中蛋白质折叠时总是倾向于将疏水基团埋藏在分子内部,将亲水基团 … WebBy comparing two magainin analogues with identical amino acid composition and similar hydrophobic moments, T.
