Dynamics and compartmentation of water in certain biosystems.
Investigation performed by nuclear magnetic resonance and by deuteration on the dynamics of water molecules in mammalian blood cells and in amphibian oocytes, muscles and nerves allowed to reveal several populations of cell water molecules. Following up relaxation and exchange processes in cell suspensions, packed cell pellets and in isolated tissues, characteristics of water dynamics and compartmentation in various biosystems are compared.
