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

... 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 will depend on the ratio of tri- and di-phosphorylated forms. Surely the only reason hydrolysis of ATP releases free energy is because the reaction ...
