Revision[edit]

I'm sorry but I think that this article needs to be re-started. I can do that later (as in days perhaps longer) based on source material such as Stryer section 14.1.4.: Structural Basis of the High Phosphoryl Transfer Potential of ATP and surrounding sections, as well as disease related references such as PMID 15282179. If anyone else would like to tackle this, be my guest. I'll not put a message on the page as ... the desire to contribute from recently acquired knowledge is excellent.

Spontaneous hydrolysis?[edit]

Does anyone know the rate on spontaneous ATP hydrolysis? --192.38.100.196 (talk) 09:14, 24 April 2008 (UTC)[reply]

Energy released?[edit]

Does anyone know how much energy is stored in ATP? (In other words, what is the energy released in the equation ATP --> ADP + energy?)

the equation is false, the energy is not "stored" in the ATP itself — Preceding unsigned comment added by 77.126.225.169 (talk) 08:34, 9 August 2011 (UTC)[reply]

The article is misleading in relation to Gibb's free energy of ATP hydrolysis. The actual energy per mol ATP depends on the concentrations of ATP, ADP and Pi. The higher the ATP and the lower the other two the more energy is available. Mg2+ and the pH also play a role. Essentially it functions like a battery that can be more or less charged. The cited -31.5 kJ/mol only apply for 1 mol of ATP, 1 mol of ADP and 1 mole of Pi, so artificial conditions. Nicholls & Ferguson is the book to read. It seems there is a recent edition: http://store.elsevier.com/Bioenergetics/David-Nicholls/isbn-9780123884312/ — Preceding unsigned comment added by 138.246.2.177 (talk) 07:33, 31 October 2016 (UTC)[reply]

Drawing resonance structure[edit]

Isn't the last structure wrong? According the drawing the O-atom that is bond with the H-atom has 10 elektrons (1 bond with H, 2 with P and 2 free elektron pairs). That isn't possible? http://guweb2.gonzaga.edu/faculty/cronk/biochem/P-index.cfm?definition=phosphate — Preceding unsigned comment added by 109.131.178.105 (talk) 19:39, 15 March 2012 (UTC)[reply]

External links modified[edit]

Hello fellow Wikipedians,

I have just modified one external link on ATP hydrolysis. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20120222051931/http://www.biologie.uni-hamburg.de:80/b-online/library/crofts/bioph354/atp_hydrolysis.html to http://www.biologie.uni-hamburg.de/b-online/library/crofts/bioph354/atp_hydrolysis.html

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

NMR related citation seems wrong[edit]

There is a sentence "In one particular study, to determine ΔG in vivo in humans, the concentration of ATP, ADP, and P_i was measured using nuclear magnetic resonance." , the reference provided isn't the study. Darien0 (talk) 13:29, 26 August 2022 (UTC)[reply]
