Question

Answer 1

Polysaccharide is a carbohydrate (e.g. starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.

Answer 2

HLO MATE HERE IS UR ANSWER

⭐. Polysaccharides are long chains of sugars.

⭐. They are threads containing different monosaccharides as building blocks.

⭐. Cellulose is a polysaccharide consisting of only one type of monosaccharide ie ., glucose .

⭐. Cellulose is a hypo polymer . Starch is a varient of this.

⭐. Animals have another varient called glycogen . Insulin is a polymer of fructose.

⭐. In a polysaccharide chain , the right end is called reducing end and left end is called non -reducing end . It has branches as shown in the form of a cartoon.

⭐. Starch forms helical secondary structures . Starch can hold I2 moles in the helical portion.

⭐. The starch - I2 is blue in colour .

⭐. Cellulose does not contain complex helices and hence cannot hold I2 .

⭐. There are more complex polysaccharides in nature.

⭐. Exoskeleton of arthropods , cell wall of fungi is chitin . Its is a complex polysaccharide .

⭐. These complex polysaccharidee are heteropolymers.
