Question

Select the correct answer from the following statemets
1. Cutin is fatty acid polymer
2. Starch is glucose polymer
3. Sucrose is monosaccharide
4. Maltose is polymer of fructose.

• A. 1, 2, 3 are correct
• B. 1 and 2 are correct
• C. 2 and 4 are correct
• D. 1 and 3 are correct

Answer 1

The correct option is B 1 and 2 are correct

Cutin is a polymer of glycerol and certain types of fatty acids. It is an integral part of the cuticle of the leaf.

Starch is formed by a-1,4 linkages between two glucose unit which is broken down during its digestion. It exist in two forms known as amylose and amylopectin. Amylose is a linear poly-D-glucose in which the monosaccharides are connected by alpha 1, 4 linkages. Amylopectin is has alpha 1, 4-glycosidic linkages with side chain branching of alpha 1,6 linkage.

Sucrose is a disaccharide formed by the glycosidic linkage between glucose and fructose. It can be broken into glucose and fructose by enzyme sucrase.

Maltose is a disaccharide formed by the glycosidic linkage between glucose monomers. It can be hydrolysed to glucose by enzyme maltase.

So, the correct answer is option B.
