In aqueous systems, polysaccharide particles can
take up water, swell, and usually undergo partial or
complete dissolution.
Polysaccharides possess a strong affinity for water
and readily hydrate when water is available.
Most polysaccharides contain glycosyl units that, on
average, have three hydroxyl groups.
Each hydroxyl group on polysaccharides has the
possibility of hydrogen bonding to one or more water
molecules. Also, the ring oxygen atom and the
glycosidic oxygen atom connecting one sugar ring to
another can form hydrogen bonds with water.
