Which of the following statements is incorrect regarding polysaccharides?
Options
- AInulin is a polymer of fructose.
- BStarch can hold iodine molecules in its helical portion.
- CIn a glycogen chain, the left end is called the reducing end.
- DChitin is a structural homopolymer found in the exoskeleton of arthropods.
Correct answer
C. In a glycogen chain, the left end is called the reducing end.
Step-by-step solution
In a polysaccharide chain such as glycogen, the right end is called the reducing end and the left end is called the non-reducing end. Therefore, the statement that the left end is the reducing end is incorrect. Inulin is a polymer of fructose. Starch forms helical secondary structures and can hold I₂ molecules in its helical portion, giving a blue colour. Chitin is a structural homopolymer of N-acetylglucosamine found in the exoskeleton of arthropods. Answer: In a glycogen chain, the left end is called the reducing
