Water in Polymers and Artemia Cysts: Relation of Neutron Scattering and NMR Results
Water is one of the major constituents in viable biological systems. An understanding of its physical properties is important to a quantitative treatment of chemical reaction rates, protein conformations, ionic distributions and other essential cellular processes. A large number of different techniques have been used to measure the properties of water in association with macromolecular systems. Some of these measurements suggest that the properties of water in these systems differ little from those of pure water, while others suggest that there are substantial changes (Drost-Hansen and Clegg, 1979). A proper interpretation of the results obtained from these techniques requires an appreciation of the heterogenous nature of the cell and the scale of distance over which variations in physical properties occur.
