Carbohydrate polymers are macromolecules built from sugar residues joined by glycosidic bonds, and the class spans storage polysaccharides, structural glycans and their synthetic derivatives [1]. Linkage position and anomeric configuration decide whether the chain is linear and ribbon-like, as in cellulose, or branched and compact, as in starch and glycogen [2]. Hydroxyl groups along the backbone make the polymers hydrophilic and able to form extended hydrogen-bond networks, which underlies their gelation and film formation [1]. Because each repeat unit carries several reactive hydroxyls, substitution at a fraction of them yields derivatives whose solubility and charge differ from the parent [1]. Molar mass and degree of substitution, rather than sugar identity alone, set the viscosity of a solution [3].
