a complex carbohydrate, as starch, inulin, or cellulose, formed by the combination of nine or more monosaccharides and capable of hydrolyzing to these simpler sugars. Also,pol`y•sac′cha•rose`(-ˌroʊs) [1890–95] Random House Kernerman Webster's College Dictionary, © 2010 K Dict...
Another mechanism is also observed during the formation of polysaccharides in bacterial antigens: first the specific repeating units are synthesized, with the participation of lipid and nucleotide carriers of sugars; polysaccharides are then synthesized from the units under the action of the enzyme ...
In the D-series of sugars, the α-form has the anomeric hydroxyl lying below the plane of the ring, while in the L-sugars, this hydroxyl lies above the ring plane in the α-form. The full name of a monosaccharide indicates whether the sugar is α or β, D or L, which kind of ...
The oxyalkylene section can be derived from alkylene glycols such as ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, and the like. The oxyalkylene section can contain a number of moles of ethylene oxide and/or propylene oxide of between 1 and 100 and prefe...
Polysaccharides categorized according to their molecular characteristics (type, number, bonding and sequence of monosaccharides), physicochemical characteristics (water solubility, viscosity, surface activity) and nutritional function (digestible or non-digestible). Polysaccharides contain only one type of monosac...
A variety ofexopolysaccharides(EPSs) are produced by a number microorganisms as an extracellular or cell surface-attached material in the form of amorphous slime (Sutherland, 1998). TheseEPSscan be categorized ashomopolysaccharidesand heteropolysaccharides (Byrom, 1991; Garcia-Ochoa, Santos, & Alcon...

5. Anti-radiation effect ginseng polysaccharide can promote the expression of superoxide dismutase and glutathione peroxidase in mice, make heme oxygenase and non-protein thiol compound return to normal, and reduce the damage of radiation to mice; can increase the number of bone marrow cells and ...
The discovery of glycoconjugate vaccines has taken place for a long time through a very empirical process. Isolated polysaccharide are structurally complex long polymers, composed of many repeating units, which can be in turn made of a singlemonosaccharide(homopolymers) or multiple sugars (hete...
4. Components of Chondroitin: Chondroitin is made up of two main sugar components: - N-acetylgalactosamine - Glucuronic acid 5. Structure of Chondroitin: Chondroitin consists of repeating units of these sugars, which can number up to 100 sugar units in length. 6. Sulfation: The sugars in ...
