A role for water in cell structure.

Abstract

The question of a role for water in biochemical and cellular events is ignored by most workers (apart from its obvious role in hydrolysis reactions, which is not under discussion here). But much recent research has pointed to the importance of physical, as well as biochemical, processes of the cell, which focus attention on such straightforward elementary questions as position and relationship in space of cell components. In this communication these questions are examined in terms of a new model of water structure. A radically new feature of this model is that water clusters have long-term rather than flickering existence and are as large as the macromolecular components of the cell. These properties allow the clusters and other components to pack together spatially so giving rise to integrated, large-scale, subcellular structures.
