"' Polysaccharides "'are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis give the constituent monosaccharides or oligosaccharides.
22.
The specific reaction involved is the hydrolysis of the 1, 4-beta-D-glycosidic linkages in cellulose, hemicellulose, lichenin, and cereal beta-D-glucans.
23.
They are generally found in their lactone form, with the ring structure essentially the same as in the original sugar's chiral anomeric carbon, and they cannot form glycosidic linkages.
24.
When the glycosidic linkages and configurations of the monosaccharides are known, they may be included as a prefix to the name, with the notation for glycosidic linkages preceding the symbols designating the configuration.
25.
When the glycosidic linkages and configurations of the monosaccharides are known, they may be included as a prefix to the name, with the notation for glycosidic linkages preceding the symbols designating the configuration.
26.
This is a versatile donor and can react with simple or carbohydrate alcohols to establish the glycosidic linkage, with reduction and " N "-acetylation of nitro group will give the targeted product.
27.
One possible reason for this is that the glycosidic linkage of trehalose, when acted upon by an insect trehalase, releases two molecules of glucose, which is required for the rapid energy requirements of flight.
28.
O-linked N-acetylglucosamine ( O-GlcNAc ) transferase ( OGT ) catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues of intracellular proteins.
29.
The nucleobases are joined to the sugars via an N-glycosidic linkage involving a nucleobase ring nitrogen ( N-1 for pyrimidines and N-9 for purines ) and the 1'carbon of the pentose sugar ring.
30.
Due to the general structure of carbohydrates, their synthesis is often preoccupied with the selective formation of glycosidic linkages and the selective reaction of hydroxyl groups; as a result, it relies heavily on the use of protecting groups.
