Preliminary examinations of dextran structures were conducted by optical rotation, infrared spectroscopy and periodate-oxidation reactions. More detailed results can be achieved by methylation analysis [19]. The hydroxyl groups are methylated with methyl iodide after activation with sodium methylsulfinyl carbanion (Fig. 2). The methyl dextran is hydrolysed to the corresponding different methylated monosaccharides, which are furthermore reduced and peracetylated. The resulting alditol acetates of methylated sugars are separated by gas chromatography and identified by their retention times. In particular, a combined capillary gas-liquid chromatography/mass... [Pg.205]

Paper electrophoresis is, even in this age of high-performance liquid chromatography (h.p.l.c.), a useful method of analysis. The equipment required is inexpensive, and the technique is simple. It lends itself well to comparison of the coordinating ability of many carbohydrates with any one cation, or of that of several cations with any one carbohydrate. The behavior of Pb proved to be typical of that of complexing cations this behavior was not fully understood by Frahn and Mills, but they made the observation that the mobility of alditols increases with increasing number of threo hydroxyl groups. ... [Pg.4]

The polymer is hydrolysed to its constituent sugars, the acid hydrolysate reduced to the alditols with NaBH4, the alditols acetylated and then analysed by gas-liquid chromatography (GLC), using a stationary phase that separates... [Pg.143]
