Abstract (EN)
NMR T?(spin-lattice) and T?(spin-spin) relaxation times in protein and enzyme solutions have been studied since 1960?s. Many approaches have been used for explaining the relaxation mechanisms. One of them is the chemical exchange of protons between free water and water bound te solids.In this study, 1/T? and 1/T? ratios of the D?O solutions, to which sucrose, maltose, pepsin and BSA were added, were studied versus concentration of added substances. It was found that 1/T? and 1/T? change linearly with concentration. Therefore, it was concluded that a fast chemical exchange occurs between bound and free water.
