Question

80. Number of glycosidic bonds in a
polysaccharide (n= number of
monosaccharides).
(1) n (2) 2n (3) n+1 (4) n - 1​

Answer 1

Answer:

Disaccharides are composed of two monosaccharide units linked together by a glycosidic bond. The most common glycosidic bonds connecting monosaccharide units are O-glycosidic bonds in which the oxygen from a hydroxyl group becomes linked to the carbonyl carbon.

Explanation:

Sucrose, lactose, and maltose are common dietary components. Lactose, the disaccharide of milk, consists of galactose joined to glucose by a β-1,4-glycosidic linkage.
