5.내용 : 


  Response of amphiphilic lipids to activity of water is studied using two classes of organized mesophases of phospholipid bilayers: stacked lipid multilayers and giant unilamellar vesicles.  In each case, molecular and mesoscale organizations of membrane lipids are directly influenced.  In membrane stacks, the three-dimensional stacking motif also organizes the chemical diversity of the lipid milieu; two-dimensional phase separation of lipids within each lamellae spontaneously couples across stacked lamellae producing columns of chemically distinct, lipid domains.  In giant vesicles, osmotic transport of water out of hypotonic vesicular compartments produces unusual pearling and self-reproduction. Osmotic swelling of hypertonic vesicles, on the other hand, produces a remarkable pulsatory dynamics of membrane domains.  Comparing these processes as elemental events in the complex working of a living cell, these findings support the idea that water is not a mere solvent for life – a blank canvas on which biomolecules become animated – but an important medium that guides biomolecular dynamics in complex, subtle and essential ways.
