Did you know?
WebA hydrophobic surface (one that has an original contact angle greater than 90°) becomes more hydrophobic when microstructured – its new contact angle becomes greater than the original. However, a hydrophilic surface … Weblong-term stabilization of hydrophilic nanoparticles in nonaqueous solvents. Here we present a general and effective polymerization– dissolution strategy for phase transfer of hydrophilic nano-particles into nonaqueous solvents by rst covalently gra ing the particle surfaces with a layer of linear-chained polystyrene
WebMany biomolecules are amphipathic, that is, they have both hydrophobic (water‐hating) and hydrophilic (water‐loving) parts. For example, palmitic acid has a carboxylic acid functional group attached to a long hydrocarbon tail. When its sodium salt, sodium palmitate, is dissolved in water, the hydrocarbon tails associate due to the ...
WebThe ionic and very hydrophilic sodium chloride, for example, is not at all soluble in hexane solvent, while the hydrophobic biphenyl is very soluble in hexane. Exercise 1. Vitamins can be classified as water-soluble or fat-soluble (consider … WebA phospholipid is an amphipathic molecule, meaning it has a hydrophobic part and a hydrophilic part. The fatty acid chains are hydrophobic and do not interact with water, whereas the phosphate-containing group is …
The hydrophobic effect represents the tendency of water to exclude non-polar molecules. The effect originates from the disruption of highly dynamic hydrogen bonds between molecules of liquid water. Polar chemical groups, such as OH group in methanol do not cause the hydrophobic effect. However, a pure hydrocarbon molecule, for example hexane, cannot accept or donate hydrogen …
