红海藻多糖的提取和结构研究

ISOLATION AND STRUCTURAL IDENTIFICATION OF A POLYSACCHARIDE OF REDSEAWEED

本文报道了从红海藻中分离提取出水溶中性多糖,经纯化和鉴定得单—木聚糖,其一级结构测定结果表明,此多糖为直链结构,以β(1—3)木糖残基连接.构象研究结果表明,该多糖具有三股螺旋结构.

A water soluble neutral polysaccharide was isolated from the Redseaweed. It was homogeneity Xylan. The primary structure was β(1→3)Xylan. Conformation was tripe helical.
