Then the tubes were added to 5 mL of four chemical solutions: solution A (SA) 0.05 M NaCl; solution B (SB) 0.6 M NaCl; solution C (SC) 1.5 M urea+0.6 M NaCl; solution D (SD) 8.0 M urea+0.6 M NaCl, which disrupted some bond types including ionic bonding, hydrogen bonding and hydrophobic interactions. Proteins were partially solubilized in these solutions to measure the existence of ionic bonds (difference between SB and SA), hydrogen bonds (difference between SC and SB) and hydrophobic interactions (difference between SD and SC).
Hydrophobic interactions, hydrogen bonding and complex formation between calcium, phosphate and phosphoserines are all involved in the gelation process (Thomar and Nicolai.
Most recently, toughness enhancement has been extensively studied with a focus on introducing hydrophobic interactions into the hydrogel system that act as reversible crosslinking points for effective dissipation against the crack energy.
These indicate that hydrophobic interaction takes place on the surface of [gamma]-[Al.sub.2][O.sub.3].
The very high van der Waals contribution (approximately -47 kcal x [mol.sup.-1]) indicated that strong hydrophobic interactions formed between the SY and the CB7 molecule.
The possible reason is that DZP-CHP (1 : 5) with the strongest hydrophobic interaction, gathered closely, is in a more stable state, for slower internal drug release.
The protease activity was observed in the retentate fraction and was purified by hydrophobic interaction chromatography on Phenyl-Sepharose CL-4B column (1.5 cm X 10 cm) equilibrated with Tris-HCl buffer (50 mM pH 7.0) containing 1.0 M ammonium sulphate (16).
The other residues impart electrostatic and hydrophobic interactions. Therefore, the interactions with these residues are imperative in identifying novel lead molecules.
In addition, R397 was found to stabilize the two aromatic residues with hydrophobic interaction.
The potential energy of hydrophobic interactions between mineral particles owing to the surfactant is much higher than that resulting from double layer or van der Waals interactions.
