摘要：
Variant xanthan gums are provided which include a water-soluble polysaccharide polymer comprising repeating pentamer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:2:1, and a water-soluble polysaccharide polymer comprising repeating tetramer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:1:1. 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.
