mix simply because they can make more favorable interactions with themselves than with the other compound The hydrophobic effect is distinctly different from this generic de-mixing So what then is the hydrophobic effect and how is it different from the simple tendency of two substances to not want to mix?
is superimposed on and often dominates the direct interaction between the solute molecules In water the unfavorable solvation free energy arises from an unfavorable entropy change associated with the reorganization of the solvent structure (the formation or strengthening of hydrogen bonds)
Hydrophobic interaction chromatography (HIC) separates proteins according to differences in their surface hydrophobicity. HIC utilizes a reversible interaction between the proteins and the hydrophobic ligand of a HIC resin. The interaction between hydrophobic proteins and a HIC resin is greatly influenced by the running buffer. A high salt concentr...
Hydrophobic interaction chromatography can be used for capture, intermediate purification, or polishing steps. Samples should be in a high salt concentration to promote hydrophobic interaction. This means HIC is well-suited for capture steps after sample cleanup by ammonium sulfate precipitation or for intermediate steps directly after an ion excha...
Hydrophobic interactions describe the relations between water and hydrophobes (low water-soluble molecules). Hydrophobes are nonpolar molecules and usually have a long chain of carbons that do not interact with water molecules. The mixing of fat and water is a good example of this particular interaction.

The shape of the hydrophobes: Aliphatic organic molecules have stronger interactions than aromatic compounds. Branches on a carbon chain will reduce the hydrophobic effect of that molecule and linear carbon chain can produce the largest hydrophobic interaction.
The interaction between hydrophobic proteins and a HIC resin is greatly influenced by the running buffer. A high salt concentration enhances the interaction. Lowering the salt concentration weakens the interaction. How does hydrophobic interaction chromatography work?
