Structured water?

[BRUNKER at DELPHI.COM]

	Please, does anyone here know of a concept called
"structured water"?

	I gather that it relates to the orientation of individual 
water molecules to some protein structures and may have some
application to anesthesia/neuron interactions...but unfortunately
there doesn't seem to be much in the literature (at least that I can
find).
	Any explanations/citations you may have will be delightedly
accepted.
	Very sincerely
	Marla Brunker
