BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The formation of an acetal (or ketal) bond between two monosaccharides is called a glycosidic bond or glycosidic linkage. Therefore, disaccharides are sugars composed of two monosaccharide units that are joined by a carbon–oxygen-carbon linkage known as a glycosidic linkage.

Detailed explanation-2: -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.

Detailed explanation-3: -Glycosidic bonds join monosaccharides or longer sugar chains to other carbohydrates, forming disaccharides, oligosaccharides and polysaccharides. It is a type of covalent bond.

Detailed explanation-4: -Glycosidic bond is a condensation reaction between two sugar units, where the H-group from one sugar interacts with the-OH group on another to release water and link the sugar units together to form a polysaccharide.

Detailed explanation-5: -An O-glycosidic bond is formed when the anomeric carbon of the sugar establishes a link with the oxygen atom in the hydroxyl group of the alcohol. If, on the other hand, the anomeric carbon of the sugar makes the link with the nitrogen atom of an amine, the bond is referred to as an N-glycosidic bond.
