    • Xylan (Polysaccharides)

      The polysaccharide “xylan” is a plant cell wall-forming polysaccharide that is the most common after cellulose.

      The backbone of many xylan in land plants has a structure in which xylose is β-(1→4) bonded. The Oligosaccharides

      obtained by enzymatic degradation of this xylan have a prebiotic effect. On the other hand, the oligosaccharides

       obtained from β-(1→3)-xylan, possessed by some green algae, have cancer cell apoptosis-inducing action.


      Xylan in Dulse

      As shown in the figure, Dulse's xylan has both β-(1→3) and β-(1→4) bonds in the backbone. The oligosaccharide

      obtained from it has a structure different from that of conventional xylooligosaccharides. And it is considered to

      have a unique health function.


      Purpose of Research

      In this study, we explore the health function of xylooligosaccharides from dulse for effective utilization of marine

      waste. Therefore, this xylooligosaccharide was prepared here. In addition, the structure of this xylooligosaccharide

      was determined.
