Based on ultra high-speed electron-crystallographic studies of water on lipid and poly-ionic surfaces, water forms transient linear elements of hydration in cubic ice conformations. Although the linear elements last for only about a million millionth of a second and are not there long enough to establish thermodynamic equilibria, they are there long enough to regulate the motions and interactions of vital molecules in living cells. By defining probability positions for water molecules on molecular surfaces, they most likely regulate motions and interactions in living cells.
