Study the given statements and select the correct answer.
(i) Right end of a polysaccharide chain is called reducing end while left end is called non-reducing end.
(ii) Starch can hold cellulose being non-helical, cannot hold iodine.
(iii) Starch and glycogen are branched molecules. (iv) Starch and glycogen are the reserve food materials of plants and animals, respectively.
Answers
Answer:
ExplanaThe right end of the polysaccharide chain which has a free reactive end and is known as reducing and left side is the non-reducing end.
Starch is a polymer of glucose that is made up of two types of chains amylose and amylopectin.
Amylose is a straight polymer with 1-4 glycosidic linkages and amylopectin is a branched polymer with 1-6 glycosidic linkage.
Starch can hold iodine molecule in the amylopectin helical structure. Starch is the reserve food material in plants. Glycogen is also a storage food material in animals. It is also branched structure, a polymer of glucose which has linear 1-4 glycosidic bonds and branched 1-6 glycosidic linkage.
Cellulose is a linear polymer of Beta D glucose which does not trap iodine molecules.
So, the correct option is 'All statements are correct.'tion:
