Water in biological systems

Does Water in Biological Systems Have a Different Structure 

It has been suggested that water in biological systems has a different structure from that of free water. Thus, Szent-Gyorgyi (the discoverer of vitamin C) was the first to suggest that an icelike structure surrounded proteins and other biomolecules. Cope examined cell hydration and asked whether water is affected by conformational 

It is interesting to notice that most of the vicinal water surrounds the elements of the cell cytoskeleton. It is not unlikely that the coherent electric waves discussed in this paper are responsible for such a correlation. Bound water also exhibits some kind of collective behavior  

It is worthwhile noticing that hysteresis has been observed in all cases in our model then the electret would appear different in subsequent cycles (alternance of Davydov and Frohlich regimes) during the cell lifetime, giving rise to a nonstationary evolution instead of a periodic one (on a time scale comparable with the lifetime of the biological system under consideration).

Although it is well recognized that the overwhelming majority of bio-- logical reactions take place in dilute aqueous solutions, very little attention has been paid to the water as a reaction partner, especially from the structural point of view. I shall discuss a few problems that are associated with the presence and the function of water in biological systems. 

In relation to the discussion of the two types of water in biologic systems bonded and unbonded the spectra of water in celluloseacetate membranes at low relative humidity (about 10%) show some indications that the first water molecules penetrating in these membranes have a higher portion of stronger H-bonded structures in comparison to the properties at higher rel. humidity.
