Abstract. Understanding membrane structure and function is one of the major unresolved problems in life science. Membranes are intimately involved in almost all biological processes including: establishing and maintaining trans-membrane gradients; compartmentalizing biochemical reactions into distinct functional domains; controlling transport into and out of cells; inter- and intra-cellular Additional Physical Format: Online version: Water transport in biological membranes.

Implementation of membranes for water treatment has progressed using more advanced membranes made from new materials and employed in various configurations. An increasing scarcity in fresh water sources fueled a push towards alternative resources such as ocean water. In the s, exploration began into using membranes for water As the First International Conference on Water and Ions in Biological Systems (Bucharest, June) was appreciated as a success, a second one was organized in the fall of the year under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO), the Romanian Academy of Medical Sciences, the Romanian Biophysical Society (Union of Societies for 14) The movement of water across biological membranes can best be predicted by E) water potentials.

Water potential can be defined as the difference in potential energy between any given water sample and pure water (at atmospheric pressure and ambient temperature).
Water potential is denoted by the Greek letter Ψ (psi) and is expressed in units of pressure (pressure is a form of The movement of fluid and solutes across biological membranes facilitates the transport of nutrients for living organisms and maintains the fluid and osmotic pressures in biological systems.

The fast and selective water transport in biological membranes is achieved by means of aquaporins, specialized trance-membrane proteins. The osmotic water permeability of aquaporins was shown to be in the range of 6×10 - 11×10 cm 3 sec -1 channel -1 for AQP1 (Saparov et al. ) and their ion rejection exceeds by far the ion Biological membranes are composed of lipid, protein, and carbohydrate that exist in a fluid state.
Biological membranes are the structures that define and control the composition of the space that they enclose.

The first living cell probably came into being when a membrane formed, separating that cell's precious contents from the rest of the universe.
Membranes defme the external boundary of cells and regulate the molecular traffic across that boundary; they divide the internal space into discrete compartments to. Finally, in tissues where water transport is regulated, the proteins are stored in intracel- lular vesicles which fuse with the plasma membrane upon a signal from a hormone such as vasopressin [lo].
