Rheological Properties of Carboxymethyl Cellulose Solutions and Gels: An Overview

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
The rheology of carboxymethyl cellulose is determined by the balance between electrostatic interactions, chain entanglements and association of unsubstituted cellulose‐like domains. The degree of substitution, substitution pattern, added salt concentration and pH determine whether solutions behave as viscoelastic liquids or weak gels.

Sulfation of Polysaccharides using Monomethyl Sulfate

Journal of Carbohydrate Chemistry, 2000
ABSTRACT The polysaccharides, curdlan, starch and dextran were sulfated when heated in DMSO with sodium methyl sulfate and a catalytic amount of H2SO4 or with pyridinium methyl sulfate. Use of diminished pressure and anhydrous CaSO4 as a desiccant improved the degree of sulfation and recovery.

Secretion of Sulfated Polysaccharides by the Gastric Mucosa

Digestion, 2009
Presence of chondroitin-4-sulfate has been demonstrated in the gastric fundic juice of the dog. It is secreted by the chief peptic cells. Chondroitin sulfate-like material was also observed in the pyloric cells of the same animal. In the dog, chondroitin-4- sulfate secretion by the fundus is increased during cholinergic stimulation but not during ...
