title: [1H- and 2H-NMR relaxation in serum albumin solutions].
abstract: The proton and deuteron relaxation times T1 and T2 were investigated in water and heavy water solutions of fatless human serum albumin. The temperature, concentration and Larmor precession frequency dependences can be well described by the conception of fast exchange in a simple biphasic model of water molecules rotation in the first hydration layer with slight anisotropy of motion. In the protonated systems the intermolecular dipole-dipole relaxation mechanism must be taken into account.
