Abstract

Values for the thermodynamic quantities (Δ F, Δ H, Δ S) in reactions in which complexes of adenine nucleotides with magnesium ion (ATPMg--, ADPMg-, AMPMg) are formed have been obtained by a microcalorimetric technique by using an isothermic Calvet's apparatus. Experimental values measured at ionic strength μ = 0.2 indicate that complex formation reactions are driven by the entropic factor and that stability of complexes increases with length of the phosphate chain.
