Polysaccharide comb-shaped, branched

The term "comb-shaped branched polysaccharide" is defined as illustrated in Figure 12. It has a linear polysaccharide backbone and pendant monosaccharide units regularly substituted on each sugar unit in the main chain.

In these respects, we expect that the well-defined comb-shaped polysaccharide [P9] will serve as a model system of naturally occurring branched polysaccharides and also as cell-specific biomedical materials using high-density p-galactose moiety as a recognition marker.
