Abstract

A least squares analysis of the titration properties of several dinucleoside monophosphates enables calculation of the p__K__'s for protonation. These p__K__'s are used to resolve the spectral properties of dinucleoside monophosphates with one base charged from the apparent spectral properties of a dinucleoside monophosphate in aqueous solution. This method is applied to dinucleoside monophosphates containing adenosine and/or cytidine. Results of CD, nmr, and CDโ€temperature dependence measurements are presented. The results indicate that singly protonated dimers of these nucleosides stack as do their unprotonated analogs. It is suggested that this is true for all dimers with one base charged.
