Cryoenzymology in aqueous media: Micellar solubilized water clusters.
Amphiphilic compounds dissolved in nonpolar organic solvents form inverted micelles whose aqueous centers can solubilize relatively large amounts of enzymes. The solutions are homogeneous and optically transparent and have low viscosity and freezing points; they provide unique and favorable systems to perform the main cryoenzymologic studies previously carried out in mixed solvents. The prepara...
متن کاملSpectrophotometric Determination of Acidity Constants of Thiamine in Water, Water-Triton X-100 Micellar Media Solutions
In this work the acidity constants of Thiamine in water and water-Triton X-100 micelle media solutions, at 25 °C, have been determined spectrophotometrically. To evaluate the pH- absorbance data, a resolution based on the combination of soft-and hard-modeling is applied. The acidity constants of all related equilibria are estimated using the whole spectral fitting of the collected data to a...
متن کاملThe experimental study of reverse micellar phase in AOT/ Heptane/ (Water or aqueous) as nano template
In this paper electrical conductivity measurements and optical investigations takes place in AOT/ heptane/ (water or aqueous) systems. The water in oil system prepared with adding water in 50% by weight of AOT/ heptane solution. In other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) Potassium Hydroxide and water were used. In each phase, the trend of the electrica...
