Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... Bond energy . All nucleoside triphosphates have ΔG°' values close to -31 kJ/mol I can see that these nucleoside triphosphates all have similar structure, so one might expect similar thermodynamic properties, and I can see how that links to similar ΔG°' values. However, actual ΔG in the cell ...
