Abstract
Alkaline treatment of a partially cyclized mu/v-carrageenan and further fractionation with potassium chloride yielded a fraction soluble in 2 M KCl with negative optical rotation. We report the analysis and some structural features of this product, such as the presence of L-galactose and 3,6-anhydro-L-galactose.
摘要
对部分环化的μ/ν-卡拉胶进行碱性处理，并用氯化钾进一步分级分离，得到了一种可溶于2 M氯化钾且旋光为负的级分。我们报道了该产物的分析结果和一些结构特征，例如L-半乳糖和3,6-脱水-L-半乳糖的存在。
