Show Answer

Answer:

Correct Answer: A

Solution:

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.
