Each energy analysis suggests that Van der Waals interaction, electrostatic interaction and hydrophobic interactions are the fundamental driving force of the binding process, and solution free energy IGsolv (37.
However, the optimal binding capacity for these proteins was seen at substantial NaCl concentrations, suggesting that the binding of these proteins is actually enhanced by hydrophobic interactions.
HAPAMs have better stability with respect to salts than unmodified ones, because the enhancement of solution polarity can strengthen the hydrophobic interactions.
Therefore, greater quantities of these amino acids in SM may have enhanced a great number of hydrophobic interactions which caused a greater amount of RUP of meal when treated with tannin.

The hydrophobic interactions are the most important non-covalent forces that are responsible for different phenomena such as structure stabilization of proteins, (18) binding of enzymes to substrates, (29) and folding of proteins.
The metachromatic effect is presumably due to the association of the dye molecules on binding with the polyanion which may involve both electrostatic and hydrophobic interactions.
Regnier; Solute and mobile phase contributions to retention in hydrophobic interaction chromatography.
TDMAC molecules are also shown to retain the neutral antibiotic vancomycin and proteins such as the tissue plasminogen activator on plastics, probably through the hydrophobic interaction (27).
Even though results of these studies have at times been contradictory because no standardized methods exist for determining surface hydrophobicity, some kind of hydrophobic interaction apparently occurs between the cell surface and the substratum that would enable the cell to overcome the repulsive forces active within a certain distance from the substratum surface and irreversibly attach.
Tosoh Corporation (Shinnanyo-shi, Japan) has patented a method for separating long chain nucleic acids such as plasmids from contaminants including protein, RNA, DNA and mixtures thereof by using hydrophobic interaction chromatography or hydrophobic interaction chromatography and ion exchange chromatography.
