In this interactive module, students investigate the structure and function of carbohydrates by assembling key polysaccharides and disaccharides. The student begins by identifying and linking monosaccharide monomers to form maltose, lactose, sucrose, glycogen, and cellulose, reinforcing an understanding of glycosidic bonds and molecular structure. As they construct these biomolecules, they explore their biological roles—such as glycogen’s function as an energy reserve in animals, lactose’s role in mammalian nutrition, and cellulose’s structural importance in plant cell walls. This hands-on activity deepens comprehension of how carbohydrates contribute to energy storage, metabolism, and structural integrity in living organisms.
