Which of the following describes the bonding in cellulose? A) Bonded by beta 1-4 glycosidic linkages. B) Bonded by beta 1-6 glycosidic linkages. C) It does not form any glycosidic linkages. D) Bonded by alpha 1-4 glycosidic linkages.
Understand the Problem
The question is asking to identify the type of glycosidic linkages present in cellulose. To answer this, we need to understand the structure of cellulose and the specific linkages that connect its monomer units.
Answer
Bonded by beta 1-4 glycosidic linkages.
The final answer is bonded by beta 1-4 glycosidic linkages.
Answer for screen readers
The final answer is bonded by beta 1-4 glycosidic linkages.
More Information
Cellulose is a structural polysaccharide and a major component of plant cell walls. The beta configuration of the glycosidic bonds allows cellulose molecules to form rigid, linear structures that stack and hydrogen bond with each other, providing strength and rigidity.
Tips
A common mistake is confusing cellulose with starch, which consists of alpha-1,4 linkages. Remember that cellulose has beta linkages, giving it a different three-dimensional structure.
