Osmotic Properties of Aqueous Solutions Containing Nucleosides

Theoretical Considerations on Mononuclear Aggregations of Mixed Nucleosides in Dilute Aqueous Solutions Based upon Osmometric Measurements

“…The investigators referred to these integers as the complexing capacity numbers; these numbers were assumed to be related to the stoichiometry of the complex. Later, the existence of the effect was confirmed with some biologically active nucleosides (2,3), few of which were reported previously to form complexes and to self-associate (4,5).…”

“…The experimental results obtained seem to fit the previous treatment for caffeine and nucleosides (1)(2)(3). Two linear slopes can also be used to express all of the data obtained, with AR as the ordinate and molal concentration as the abscissa.…”

“…The lifetime is so be different from that of another because of various factors, including those that are inherent in the molecules themselves, such as size, aromaticity, polarizability, polarity, potential hydrogen bonding sites, and other physicochemical properties (14, 15). The concentrations used for the study of self-association were all 0.1 molal and lower; the nucleoside mixtures were all 0.2 molal and lower (2,3). Very dilute solutions were preferred over concentrated solutions to trace this effect and also to obtain a better picture of the behavior.…”

“…Standardization-The method was fully described previously (1)(2)(3). A value of 923.7 ohms/molal for the slope of the standard solution of sucrose is used for this work.…”

Interactions of nucleic acid bases with catechol: UV studies

“…Furthermore, Borazan (23), in explaining experimental results on complexation of the naturally occurring nucleosides and related compounds in dilute aqueous solutions (24)(25)(26)(27), pointed out that multiple consecutive equilibria possibly can exist. Thus, for similar systems, such as the present case, plots of Eq.…”
