Dear BUMmers,
I am looking for some info on the bond
energy of the P-O bonds in adenosine
triphosphoric acid (ATP). Though this
is not directly an NMR question, it is
related to my 31P NMR experiments on
bacterial phosphorus metabolites
(http://www.fz-juelich.de/ibt/flux/coryne-phosphorous.html).
To be more precisely:
what is the bond energy of P-O in
ATP: Ade(nosine)-Rib(ose)-O-P(O2H)-O-P(O2H)-O-P(O2H)OH,
ADP: Ade-Rib-O-P(O2H)-O-P(O2H)OH,
AMP: Ade-Rib-O-P(O2H)-OH
I AM NOT LOOKING FOR THE ENERGY TO
HYDROLYZE AN ORTHOPHOSPHATE, say from
ATP to yield ADP and Phosphate (you find
the answer in every textbook of biochemistry),
but for the energy to break the P-O bonds
in the gaseous phase!
Ade-Rib-O-P(O2H)-O-P(O2H)-O-P(O2H)OH
plus energy yields
Ade-Rib-O-P(O2H)-O-P(O2H)-O. plus .P(O2H)OH,
Ade-Rib-O-P(O2H)-O-P(O2H)O.
plus energy yields
Ade-Rib-O-P(O2H)-O. plus .P(O2H)O.
Can anybody help?
Thanks,
Siggi
