When you pass around the side dishes at this year's Thanksgiving feast, here's one thing to be thankful for: you're eating mashed potatoes instead of mashed paper towels. But if you were chewing on the towels instead of the spuds, would you even know it.
Because a Paper towel is made like a towel, it is manmade. Potatoes are natural things therefore different.
Paper towels are primarily made of cellulose, which is a polymer of glucose known for its absorbent properties. Potatoes, on the other hand, contain starch, which is also a glucose polymer but serves as energy storage in plants. This difference in chemical structure leads to distinct functions: absorbency in paper towels versus energy storage in potatoes.
