Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of linkage is present in polysaccharides?
A
Ether
B
Glycosidic
C
Ester
D
Peptide
E
Amide
Explanation: 

Detailed explanation-1: -Glycosidic linkage is the type of linkage between adjacent glycosylation on the main chain of polysaccharides [114].

Detailed explanation-2: -Glucose-(1 → 4)-glucose is the backbone glycosidic linkage in three abundant biological storage polysaccharides: amylose, amylopectin, and glycogen. Experimental and computational investigations have shown that the (1 → 4)-glycosidic bond in glucans is conformationally restricted.

Detailed explanation-3: -“The two monosaccharides are joined together by an oxide linkage formed by the loss of a water molecule. Such a linkage between two monosaccharide units through an oxygen atom is called glycosidic linkage.”

Detailed explanation-4: -Amylose is a straight-chain polymer that have D−glucose units joined together by −glycosidic linkage.

Detailed explanation-5: -Cellulose is a linear homopolysaccharide of D-glucose units, which are linked together by beta-1, 4 glycosidic bonds.
