title: [The effect of structure and conformation on the relative hydrophobicity of dinucleosidephosphates and their analogs].
abstract: Partition of a number of dinucleosidephosphates, their (2'-5')-isomers and a series of their analogues, in which the ribose ring was replaced by acyclic hydroxyalkyl substituents, in an aqueous biphasic ficoll--dextran system has been studied. Effect of the ionic composition of the biphasic system on partitioning of the compounds was examined. The relative hydrophobicity of the compounds in the presence of 0.11 M phosphate buffer, pH 7.4, and in the presence of 0.15 M NaCl in 0.01 M buffer, pH 7.4, was estimated. The results obtained are considered in regard to the effect of structure and conformation of a molecule on its affinity for an aqueous environment.
