The way I've heard it, the altered physical properties of deuterium 
bearing molecules can have a profound effect on processes that take 
place on or near biological membranes.  Supposedly, consuming large 
quantities of D20 can be harmful or even fatal, but in this case, 
"large" means more than most of us are ever likely to see in our
