“Furthermore, when the OVA was as a carrier, the solubility of curcumin has been increased ~370 times to 32.73 μg/mL compared to that of free curcumin at pH 7.0.”
“The results suggested that the binding included two steps: first, curcumin molecule entered into the hydrophobic pocket of OVA by hydrophobic interaction; and second the interaction was enhanced via hydrogen bonds, resulting in static fluorescence quenching and secondary structural change of OVA.”
