Β Lactoglobulin

The rate of oxidation of β-lactoglobulin with ferricyanide decreases markedly as the concentration of sodium dodecyl sulfate is increased from 0.25 to 1.0%, whereas the detergent concentration has little effect on the rate of oxidation of this protein by o-iodosobenzoate and 2,6-dichlorophenol indophenol. It is suggested that the structure of this protein in sodium dodecyl sulfate, coupled with the steric effect of bound detergent molecules, hinders the formation of a transition state involving the sulfhydryl group, a heavy metal ion, and the ferricyanide ion.

The solubility of chlorophenols as affected by surfactant was investigated. Three kinds of surfactant, sodium dodecyl sulfate, Triton X-100, and Brij 35, were utilized. The solubilization of chlorophenols by surfactant follows the order of 2,4,6-trichlorophenol > 2,4-dichlorophenol > 2,6-dichlorophenol > 2-chlorophenol; and the critical micelle concentration is an important index. The adsorption reactions of 2,4-dichlorophenol and 2,4,6- trichlorophenol onto hydrous montmorillonite in the presence of surfactant were examined. The presence of surfactant decreased the adsorption of chlorophenols significantly. The roles of hydrophobicity of chlorophenols in solubilization and adsorption behaviors are discussed.
