Common processed paper primarily consists of cellulose, a polymer made up of repeating units of the molecule C6H10O5. The structure of cellulose is characterized by long chains of glucose units linked by β(1→4) glycosidic bonds, which contribute to its strength and rigidity. The polymerization of cellulose allows for the formation of extensive networks, enhancing the material's properties. The discussion highlights the significance of cellulose in paper production and its molecular structure, emphasizing its role as the primary component in processed paper.
