The absence of which structure in cellulose does not allow it to hold iodine molecules? Correct Answer Helix

Iodine molecules are held in helices of polysaccharide structures such as starch. The secondary structure of starch is helical and can hence hold starch. Cellulose has a linear structure and thus, cannot hold iodine molecules.
