✦ Synopsis

Water proton transverse relaxation times (T 2 ) and self-diffusion coefficients (D) were measured in randomly oriented hydrated collagen fibers. Three T 2 relaxation times were discerned indicating the presence of at least three water fractions in the collagen sample. The D values associated with each water fraction were determined. The diffusion time dependence of D suggests water motion is restricted by macromolecular structure. The experimental results are discussed with reference to the structural properties of hydrated collagen fibers.
