【聚蔗糖專題】：

聚蔗糖是一種無毒、無害、非易燃易爆白色粉末狀的水溶性高分子化合物。

?

The molecules are highly branched and thehigh content of hydroxyl groups leads to very good solubility in aqueous media.Polysucroses behaves as an ideal neutral sphere and has been proposed as themolecule of choice for studying pore size distribution and the permeability ofmembranes.

蔗糖殘基中的糖苷鍵是決定多糖穩(wěn)定性的主要因素。多糖不含任何離子化基團(tuán)，因此結(jié)構(gòu)不會在生理?xiàng)l件下發(fā)生反應(yīng)。在堿性和中性溶液中穩(wěn)定，但在pH值為3的溶液中迅速水解，特別是在較高的pH值下溫度。強(qiáng)應(yīng)避免使用氧化劑和還原劑。聚硅氧烷是一種干粉，具有極強(qiáng)的親水性。溶液的最佳制備方法是將聚硅氧烷緩慢攪拌到水緩沖液中。可能需要溫和加熱才能完全溶解。

The stability of Polysucroses is chieflydetermined by the glycosidic bonds in the sucrose residues. Polysucrose doesnot contain any ionized groups, so the structure does not react underphysiological conditions. It is stable in alkaline and neutral solutions, butis rapidly hydrolyzed in solution at pH 3, especially at elevated temperature.Strong oxidizing and reducing agents should be avoided. Polysucrose is providedas a dry powder and is extremely hydrophilic. Solutions are best prepared byslowly stirring Polysucrose into aqueous buffer. Gentle heating may be requiredfor complete solubilization.
