atp, magnesium

[kellbrook]

they say atp is the energy currency of the cell, does atp always come as atp-mg2 ?

ATP itself does not contain Mg. However, ATP that is found in complexes often contains Mg- but not covalently bound.

I think so... Indeed, the real substrate for enzymes that use ATP is never the ATP molecule, but is the complex ATP-Mg2+. This ion is important for electric charge shielding of the phosphate groups.

[kellbrook]

inside the body can atp exist as atp alone or does it always have to be attched to something like magneisum?
