Determination of the Structure of Water in Collagen on Basis of 1H and 2H NMR Data
It is shown on the basis of 1H and 2H NMR data that the constituent water in native collagen is characterised by the structure close to the structure of common liquid water. The exception is the boundary water layer on the “surface” of polypeptide macromolecules, where H2O positions are determined mainly by the arrangement of uncontracted OH,NH and CO groups.
