Read the following statements regarding polysaccharides: (A) Starch forms helical secondary structures. (B) Cellulose can hold iodine molecules in its helical portion. (C) Inulin is a polymer of fructose. (D) Plant cell walls are made of cellulose. How many of the above statements are correct?

Step-by-step solution

Statement (A) is correct as starch forms helical secondary structures. Statement (B) is incorrect because cellulose does not contain complex helices and hence cannot hold iodine molecules. Statement (C) is correct as inulin is a homopolymer of fructose. Statement (D) is correct as plant cell walls are made of cellulose. Therefore, exactly three statements are correct. Answer: Three
