Cellulose shows up many times in our daily lives. It’s composed of hundreds of glucose molecules, making it a polysaccharide. Normally, cellulose is in cell walls in plants, being white strands of fiber. It’s found in wood, cotton, flax, etc. One of it’s properties is that despite being a hydrophile, it’s insoluble in water. Cellulose is also biodegradable, and can be broken up into glucose molecules using chemicals. It is found in everything containing plant material, including wood and cotton. Those materials are almost always in the fabric we use and wear daily, and plant material is often everywhere we look.
