Interpretation Introduction

Interpretation: The most abundant carbohydrate on earth and its sources are to be explained.

Concept introduction: Polysaccharides are long polymer chains made by joining monosaccharide molecules.

Answer to Problem 15LC

The most abundant carbohydrate on earth is cellulose, which is found in the cell walls of plants and algae.

Explanation of Solution

Cellulose is the most abundant form of carbohydrate found on earth. Cellulose is an example of a polysaccharide. The main constituent of cellulose is a linear polymer that is composed of glucose units connected to one another by $\text{1,4-}$ glycosidic linkages.

Cellulose is found in the cell walls of plants and algae. It provides the plants with stability as well as increased mechanical strength.

Conclusion

The most abundant carbohydrate on earth is cellulose, which is found in the cell walls of plants and algae.
