Question

which of the following has not glycosidic linkage
(a)Maltose
(b)Amylose
(c)Galactose
(d)Sucrose

Answer 1

• Lactose is a disaccharide of two galactose and glucose. It has beta 1,4-glycosidic linkages.

Answer 2

Glycosidic linkage is not present in GALACTOSE sugar. (OPTION C)

GLYCOSIDIC LINKAGE -

• A covalent bond that joins carbohydrate molecules.
• One sugar is joined with another sugar by the formation of a glycosidic bond.
• Maltose sugar is a disaccharide carbohydrate in which glucose units are joined by an alpha 1,4 glycosidic bond.
• Amylose sugar is a polysaccharide carbohydrate in which sugar molecules are bonded together by an alpha-glycosidic bond.
• Sucrose is a disaccharide sugar in which glucose and fructose molecules are bonded by alpha-1, beta-2 glycosidic linkage.
