Final answer:
Cellulose is the most abundant natural biopolymer found in plant cell walls, made up of glucose monomers linked by B 1-4 glycosidic bonds. It provides structural support and can be found in wood, paper, and cotton.
Step-by-step explanation:
Cellulose: The Most Abundant Natural Biopolymer
Cellulose is the most abundant natural biopolymer, making up the cell walls of plants and providing structural support. It is made up of glucose monomers linked by B 1-4 glycosidic bonds. Unlike humans, plants do not have the enzyme cellulase to digest cellulose, but it adds bulk to their diet and aids in gastric motility.
Examples of cellulosic materials include wood, paper, and cotton.
