Polysaccharides are

• A. monosaccharides bonded by hydrogen bonds
• B. few monosaccharides bonded by glycosidic bonds
• C. many monosaccharides bonded together by peptide bonds
• D. many monosaccharides bonded together by glycosidic bonds to form long polymers

Answer: (D)

Polysaccharides are long polymers made of monosaccharides joined by glycosidic bonds. The glycosidic bond is a covalent link formed when two sugar units are connected through a dehydration reaction, typically between the anomeric carbon of one sugar and a hydroxyl group of the next. This covalent linkage creates a chain of many sugar units, which can be linear or branched, giving rise to polymers like starch, glycogen, and cellulose. Hydrogen bonds can stabilize the structure, but they do not join the monomers themselves. Peptide bonds link amino acids in proteins, not sugars. So the idea that many monosaccharides bonded together by glycosidic bonds to form long polymers correctly defines polysaccharides.
