Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Classification of carbohydrates that contains many monosaccharide units covalently bonded to each other.
A
Monosaccharide
B
Disaccharide
C
Oligosaccharide
D
Polysaccharide
Explanation: 

Detailed explanation-1: -Polysaccharides contain a large number of monosaccharide units bonded to each other by a series of glycosidic bonds.

Detailed explanation-2: -Polysaccharides. A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly-= “many”).

Detailed explanation-3: -Disaccharides. 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-4: -Carbohydrates are divided into three categories: Monosaccharide– Monosaccharide includes glucose and galactose. Disaccharide-Disaccharide includes sucrose and maltose. Polysaccharide-Polysaccharide includes starch, glycogen, and cellulose.

Detailed explanation-5: -Disaccharides (C 12H 22O 11) are sugars composed of two monosaccharide units that are joined by a carbon–oxygen-carbon linkage known as a glycosidic linkage. This linkage is formed from the reaction of the anomeric carbon of one cyclic monosaccharide with the OH group of a second monosaccharide.
