Paper Abstract

A stepwise hydration of bovine serum albumin is studied using infrared spectroscopy. For determination of the configuration interactions of hydrating H20 molecules to specific protein parts evaporation spectra were used. Evaporation spectra were calculated by subtraction of the spectra of hydrated protein from the spectrum of the dry protein. Evaporation spectra are further processed with a novel method, which is based on the decomposition of the original spectra into basic vectors (spectra). For detailed assignment of the basic spectra the temperature measurements and H/D exchanged were used. Upon the assignment of the basic vectors several interaction configurations of H20 molecules attached to specific protein sites as a function of the hydration level were proposed.
