"INSIDE THE CELL, the concentration of proteins in cytoplasm is between 170 to 300 mg/ml, which suggests that 7 to 9 shells of water (hydration shells) coat the available surfaces, corresponding to a distance of 4 to 5nm (nanometre, 10(-9) m) between the surfaces. A substantial fraction of the water is quite closely associated (at a distance of less than 0.5nm) with the proteins, nucleic acids, polysaccharides and assemblies of smaller molecules that make up an organism, and is essential for their functioning." http://www.i-sis.org.uk/WFMEZ.php View in LinkedIn
