DETERMINATION OF COMPLEXATION CONSTANT FOR CHOLESTEROL-DIISOPROPYL SULFOXIDE COMPLEX BY IR SPECTROSCOPY METHOD
IR absorption spectra have been studied for cholesterol in tetrachloromethane in the presence of diisopropyl sulfoxide. The complex formation between cholesterol and diisopropyl sulfoxide is shown to occur through the OH…O=S hydrogen bond. The complexation constant for the cholesterol-diisopropyl sulfoxide complex was found to be 9.25 l/mol at 23 ° С.
