Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the name of the bond that forms between monosaccharides in a disaccharide?
A
glycosidic bond
B
peptide bond
C
ester bond
D
glucose bond
Explanation: 

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.

Detailed explanation-3: -Glycosidic Bond Formation Two monosaccharide units can be joined together by a glycosidic bond-this is the fundamental linkage among the monosaccharide building blocks found in all oligosaccharides. The glycosidic bond is formed between the anomeric carbon of one monosaccharide and a hydroxyl group of another.

Detailed explanation-4: -Carbohydrates are made up of monosaccharides linked together into polysaccharide chains by a type of covalent bond known as a glycosidic bond. These glycosidic bonds are formed in a dehydration synthesis reaction.

Detailed explanation-5: -Glycosidic bonds join monosaccharides or longer sugar chains to other carbohydrates, forming disaccharides, oligosaccharides and polysaccharides. It is a type of covalent bond.
