A freeze-drying method enabling solubilization of hydrophobic species in aqueous solutions of native hyaluronan is described. The method is based on opening the access to supposed hydrophobic patches on hyaluronan by disturbing its massive hydration shell. Hydrophobic and/or polarity-sensitive fluorescence probes were used as hydrophobic models or indicators of interactions with hydrophobic pat...

In this study, changes in hydrophobic interactions among gluten proteins were analyzed during dough mixing. Size-exclusion high-performance chromatography and two-dimensional fluorescence difference gel electrophoresis performed on extracted with 1-propanol by weakening the interaction. The amount of 30% increased from start mixing to peak consistency, suggesting that strongly aggregated weaken...

The design of molecularly imprinted polymers (MIPs) for the specific binding hydrophobic molecules (mitotane) was investigated by considering monomers and cross-linking agents with variable character, methyl methacrylate, butyl methacrylate lauryl as functional monomers, ethylene glycol dimethacrylate 1,6-hexanediol agents. MIPs were bound to a porous silica support means radical transfer react...

We examine a new approach to reversibly modulate hydrophobic interactions in associative polymers using cyclodextrins (CD) and enzymes that cause scission of the a-1, 4 linkages in cyclodextrins. The associative polymers have a comb-like structure with pendant hydrophobic groups randomly attached to the polymer backbone. The intermolecular interaction between hydrophobic groups forms a transien...

The hydrophobic effect stabilizes the native structure of proteins by minimizing the unfavorable interactions between hydrophobic residues and water through the formation of a hydrophobic core. Here, we include the entropic and enthalpic contributions of the hydrophobic effect explicitly in an implicit solvent model. This allows us to capture two important effects: a length-scale dependence and...
