 Wendy,

The answer to your first question is easy, the chemical formula is H2O, 
the same as for plian water. The only difference is in the Hydrogen atom, 
since it has a neutron in addition to the proton in its nucleus.
I don't think that there is an answer to your second question. As far as 
I know there are no animal (and of course, no human) study on this 
subject. As a guess, there are probably no side effects, but that is only 
a less than educated guess.
Good luck.
