Which of the following correctly describes polysaccharides?

• A. Single sugar units
• B. Two monosaccharides linked together
• C. Long chains of sugar molecules
• D. Short chains of fatty acids

Answer: (C)

Polysaccharides are indeed characterized as long chains of sugar molecules, which are comprised of numerous monosaccharide units linked together through glycosidic bonds. This structural definition highlights their complexity compared to simpler carbohydrates like monosaccharides (single sugar units) and disaccharides (two linked monosaccharides). In polysaccharides, thousands of monosaccharides can be connected to form these extensive chains, which play crucial roles in biological systems. For example, starch and glycogen serve as energy storage in plants and animals, respectively, while cellulose provides structural support in plant cell walls. Understanding polysaccharides as long chains emphasizes their functionality in both energy storage and structural roles within various organisms.
