Frequently Asked Questions

What exactly is cellulose?
Cellulose is a complex carbohydrate, or a polysaccharide, that plants produce. It serves as a critical structural component of plant cell walls, giving plants strength and rigidity. Essentially, cellulose is what makes plants stand up straight and reach towards the sun.
How do humans use cellulose?
Humans have found numerous uses for cellulose, from food to clothing and even building materials. In the food industry, cellulose is used as a stabilizer and thickener. For clothing, cellulose from cotton plants is spun into thread and woven into fabric. Additionally, cellulose is a key ingredient in making paper and cardboard.
Can humans digest cellulose?
No, humans can't digest cellulose because we lack the enzyme necessary to break it down. This substance passes through our digestive system undigested, acting as dietary fiber, which aids in digestion and helps us feel full.
Is cellulose only found in plants?
Primarily, yes, cellulose is found in plants, where it's a major component of the cell wall. However, some bacteria and algae also produce cellulose, but the vast majority of cellulose comes from plant sources.
How does cellulose benefit the environment?
Cellulose benefits the environment in several ways. For starters, it's biodegradable, meaning it can break down naturally without harming the planet. Also, plants use carbon dioxide from the air to make cellulose, which helps reduce greenhouse gases. Lastly, because it's a renewable resource, using cellulose instead of synthetic materials can help decrease our reliance on fossil fuels.
What's the difference between cellulose and starch?
Both cellulose and starch are polysaccharides found in plants, but they serve different purposes and have different structures. Starch is used by plants as a way to store energy, and humans can digest it to use that energy. On the flip side, cellulose provides structural support to plant cell walls. Structurally, the glucose units in starch are connected in a way that is digestible by humans, whereas the bonds in cellulose cannot be broken down by human digestive enzymes.
How is cellulose used in medicine?
In medicine, cellulose is used in a variety of ways. It's an ingredient in some pharmaceuticals, serving as a filler or to control the release of active ingredients. Cellulose derivatives, like hydroxyethyl cellulose, are used in eye drops as a lubricant. Additionally, cellulose materials can be used in wound dressings due to their absorbency and biocompatibility.
