question: The chains in cellulose stack in parallel rows held together by hydrogen bonds between which groups?
distractor3: soda groups
distractor1: disc groups
distractor2: carbon groups
correct_answer: hydroxl groups
support: that produce a coiled structure. The glucose units in cellulose, in contrast, are linked to give long, unbranched chains. The chains in cellulose stack in parallel rows held together by hydrogen bonds between hydroxyl groups. This arrangement produces a rigid structure that is insoluble in water.
