疏水键(Hydrophobic interaction) 1. 疏水键即疏水作用力是指非极性基团或物质在水溶液里排除水分子,彼此 聚合在一起的倾向(or hydrophobic interaction, is the observed tendency of nonpolar groups or substances to aggregate in aqueous solution and exclude water molecules) 2. 疏水作用的形成源自热力学第二定律...
疏水作用 The Hydrophobic Effect :The aggregation of nonpolar groups in water leads to an increase in entropy owing to the release of water molecules into bulk water.Water molecules that are in contact with hydrophobic surfaces form ‘cages’ around the n
In chemistry, hydrophobicity refers to the physical property of a molecule (hydrophobe) and water to repel each other. Hydrophobic molecules usually gather together in water, and the water forms a droplet shape with a large contact angle on the surface of the hydrophobic solution.Water molecules ...

Molecules with both hydrophilic andhydrophobicgroups are called amphipathic or amphiphilic. 分子兼有亲水的和疏水的两个基团,叫做两性的或两亲的. 辞典例句 Methane is said to behydrophobic. 甲烷被称为疏水的. 辞典例句 The substance is extremelyhydrophobicand therefore exhibits some unique properties in wat...
the water forms a transient microscopic hydration shell which shows extensive structural ordering resembling that in ice and clathrates. Thus, we presume that this strong H-bond network of water molecules can squeeze out the hydrophobic reactants39. This water-induced confinement effect can consequent...

Hydrophobic molecules are nonpolar. When they are exposed to water, their nonpolar nature disruptshydrogen bondsbetween water molecules, forming a clathrate-like structure on their surface. The structure is more ordered than free water molecules. The change inentropy(disorder) causes nonpolar molecules ...
Water molecules in close contact with the LCO surface form a strongly adsorbed layer, which leads to a free energy barrier for the adsorption of polar or charged molecules to the LCO surface. Moreover, due to the strong hydrogen bonding interactions with the LCO surface, the first water layer...
Redistribution of ordered water molecules around singleapolarsolutes back into bulk solution causes the association of apolar molecules in water and the decrease of theGibbs energyof the system, which is termed ashydrophobic interaction. This interaction exists between hydrophobic groups such asbenzene rin...
