Abstract

Abstract: Two approaches were taken to determine the intramolecular stacking equilibrium quotients in aqueous solution at 25 OC for 1, N6-ethenoadenylyl-(3'+ 5')-1, P- ethenoadenosine (cApcA), one involving measurements of the temperature dependence of the ultraviolet absorption spectrum and the other, measurements of the ionization constants of tApcA and the component monomers. The values estimated by these two alternative ...
