摘要：
Compositions are provided which include a water-soluble polysaccharide polymer having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:2:1. The D-glucose moieties are linked in a beta-[1,4] configuration. The inner D-mannose moieties are linked in an alpha-[1,3] configuration, generally to alternate glucose moieties. The D-glucuronic acid moieties are linked in a beta-[1,2] configuration to the inner mannose moieties. The outer mannose moieties are linked to the glucuronic acid moieties in a beta-[1,4] configuration. Processes for preparing the polysaccharide polymers are also provided.
