Read the passage carefully and answer.

Carbohydrates are essential for both plants and animals. Some common examples of carbohydrates are glucose, fructose, sucrose, glycogen, cellulose and starch. They form a major portion of our food. Honey has been used for a long time as an instant source of energy in Ayurvedic medicine. Carbohydrates are used as storage molecules in both plants and animals. The cell wall of bacteria and plants is made of cellulose. We use cellulose in the form of wood for making furniture and as cotton fiber for clothing. They also provide raw material for textiles, paper, lacquers, and breweries. Carbohydrates are classified as Monosaccharides, Oligosaccharides and Polysaccharides on the basis of their behavior towards hydrolysis. Monosaccharides cannot be hydrolyzed further to simpler units whereas oligosaccharides can yield 2-10 units of monosaccharides on hydrolysis. Polysaccharides, which are non-sugars yield a large number of monosaccharide units on hydrolysis.

Answer the following questions about carbohydrates:

Pick the incorrect statement from the following:

Amylopectin contains only 1,3-glycosidic linkage

The correct answer is Option (1) → Amylopectin contains only 1,3-glycosidic linkage **

• Amylopectin contains α-1,4 glycosidic linkages in the main chain and α-1,6 glycosidic linkages at the branch points.
• It does not contain 1,3-glycosidic linkages.

The other statements are correct:

• Amylopectin is insoluble in water 
• Amylopectin is the major constituent of starch
• Amylopectin has a branched chain structure 

 Correct answer: Amylopectin contains only 1,3-glycosidic linkage
