ATP's new role in human health and disease...

As a undergraduate student, every microbiology/biochem professor i ever had relentlessly drilled into our heads: ATP=energy. Written in my notes on the side margin (and going round and round through my head as i crammed for tests ignored until the last minute) was: ATP=energy, ATP=energy, ATP=energy.
It's true, cells all over our body use Adenosine triphosphate for energy by ripping off one of the phosphate groups somehow (kinda had to reach back to remember that fact.) But, after decades of research into ATP receptor molecules, it seems there is a new way to look at our old familiar adenosine.
