Amylose vs. Cellulose: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Published on November 6, 2023
Amylose is a linear polymer of glucose found in plants, mainly as a component of starch, while cellulose is a complex carbohydrate that forms the primary structural component of green plants.
Key Differences
Amylose and cellulose are both polysaccharides, which means they are large molecules made up of smaller sugar units. However, their structures, functions, and places in the natural world distinguish them significantly from one another. At their core, the primary difference lies in their molecular arrangement and purpose in plants.

Amylose is a component of starch, which is the stored energy of plants. It is primarily found in seeds and tubers where plants store energy for future use. Amylose is a straight chain molecule, comprised of glucose units connected by α-1,4-glycosidic bonds. This linear structure allows it to be more compact, making it perfect for storage purposes.

Cellulose, on the other hand, is a structural molecule in plants, providing rigidity to the cell walls of green plants, ensuring they can stand upright and resist external pressures. Unlike amylose, cellulose is a linear chain of glucose units too, but they are connected by β-1,4-glycosidic bonds. This configuration gives cellulose its strength and rigidity, making it essential for the plant's structural integrity.

The human digestive system responds differently to amylose and cellulose. While enzymes in our bodies can break down amylose into usable sugar, humans lack the necessary enzymes to digest cellulose. This is why we can obtain energy from consuming starch-rich foods but consider cellulose or dietary fiber as indigestible.

In the broader scope, both amylose and cellulose play pivotal roles in nature. Amylose provides energy reserves for plants, which in turn nourish animals and humans. Cellulose, being a primary component of plant cell walls, supports the growth and sustenance of immense forests and plant-based ecosystems, reinforcing the interconnectedness of life on Earth.
