I: | Cellulose is a polymeric polysaccharide consisting of only one type of monosaccharide. |
II: | Starch is a homopolymer. |
III: | Inulin is a polymer of fructose. |
IV: | In glycogen, the right end is called the reducing end, and the left end is called the non-reducing end. |
Assertion: | The starch-I2 is blue in colour. |
Reason: | Starch forms helical secondary structures and can hold I2 molecules in the helical portion. |
