What type of bonds are found as a result of dehydration synthesis of two monosaccharides?
A
nonpolar covalent bond
B
glycosidic linkage
C
ionic bond
D
hydrogen linkage
Explanation: 

Detailed explanation-1: -Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond.

Detailed explanation-2: -A glycosidic linkage is defined as a covalent bond created by a dehydration reaction between two monosaccharides. The resulting product is called a disaccharide.

Detailed explanation-3: -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-4: -The addition of carbohydrates to a molecule is via the formation of a glycosidic bond, which is a form of dehydration synthesis. There are four types of glycosidic bonds, the C-, S-, N-and O-glycosidic bonds.

Detailed explanation-5: -The name given to the covalent bond between the two monosaccharides is a glycosidic bond. Glycosidic bonds form between hydroxyl groups of the two saccharide molecules.
