Modification of Poly- and Oligosaccharides with Os(VI) pyridine. Voltammetry of the Os(VI) Adducts Obtained by Ligand Exchange
Polysaccharides and oligosaccharides were modified with Os(VI)pyridine complex followed by ligand exchange with different ligands such as 2,2-bipyridine or N,N,N,N-tetramethylethylenediamine. The time of the modification was much shorter (taking about 15min) then direct modification with the given Os(VI) complex. The resulting saccharide adducts were analyzed by voltammetric methods at carbon and mercury electrodes. The results showed that the proposed technique gives promise for a new approach to analysis of glycoproteins.
