Partitioning of oligoglucans in SEPHADEX G-15 (cas 11081-40-6) in relation to their conformational structure

Add time:07/21/2019    Source:sciencedirect.com

There is good evidence that, in Sephadex gels, oligosaccharide series how (positive) linear free energy relations with respect to the degree of polymerisation. The distribution coefficients of disaccharides are thus a measure of the differences between the polyglucan series to which they belong. The partitioning in SEPHADEX G-15 (cas 11081-40-6) of eight diglucosides was studied. Their distribution coefficients could be arranged in four paris. The eight corersponding polyglucan series can also be classified into four pairs, both members of each pair having a similar conformational structure. Further, the order of the pairs of distribution coefficients seemed to be well matched to the conformational pairings. This partitioning pattern is probably not confined to the homogeneous disaccharides, because differences between the diglucosides were similar in two cases to differences between corresponding heterogeneous disaccharides. However, it is concluded that it would be incautious to attribute the order of the disaccharide distribution coefficients purely to different degrees of steric exclusion.
