Product introduction
右旋糖酐是一种无水葡萄糖的聚合物。由大约95%的α-D-(166)键组成。其余的 a (163) 键合解释了葡聚糖的分支。分支长度上的冲突数据意味着平均分支长度小于 3 个葡萄糖单位。但是,其他方法表明存在大于 50 个葡萄糖单位的分支。已发现天然右旋糖酐的分子量 (MW) 在 900 万至 500 万范围内。较低分子量的右旋糖酐将表现出略微较少的支化 ,并具有更窄的分子量分布范围。分子量大于10,000 的葡聚糖似乎是表现为高度支化的。随着分子量的增加,葡聚糖分子的对称性增强。具有2,000至10,000分子量的葡聚糖表现出了可膨胀线圈的特性。在分子量低于2,000 时,右旋糖酐更像棒状。右旋糖酐的分子量用以下一种或多种方法测定:低角度激光散射、尺寸排阻色谱法、铜络合和蒽酮试剂显色还原末端糖的测定和粘度。 产品规格与参数: SKU
