Question

Which is not a polysaccharide?

• A. Sucrose
• B. Starch
• C. Glycogen
• D. Cellulose

Answer 1

The correct option is A Sucrose

Sucrose is not an example of polysaccharides. Sucrose, commonly named table sugar or sugar, is cane and beet sugar. The molecule is a disaccharide; combination of the monosaccharides glucose and fructose with the formula C${}_{12}$H${}_{22}$O${}_{11}$. On the other hand, hydrolase is an enzyme that catalyzes the hydrolysis of a chemical bond. Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis give the constituent monosaccharides or oligosaccharides.
