Paper Abstract

In recent years, it has become apparent that the ubiquitous carbohydrates of living matter perform a much broader biological role. This has stimulated the interest in examinations of the interactions between carbohydrates and metal ions. Some researches have shown that metal ions can coordinate to 0-1 and 0-2 hydroxyl groups of glucose and water molecules in cation/D-glucose complexes. The strong, sugar H-bonding network is rearranged upon D-glucose adduct-formation , and the a-anomeric configuration is favored by these metal ion coordinations1.In the present investigation, we have undertaken FT-IR spectral studies on cation/D-glucose samples in glassy state. A series of compounds including I A , II A , first row transition metal and lanthanide(Ln) chlorides were used to preapre the samples by the methods analogous to those of ref. 2. The IR spectra were recorded in the 4000-400cm-1 region with a Nicolet 7199B FT-IR spectrometer.
