The correct definition of a polysaccharide is indeed a complex carbohydrate made of many sugar molecules. Polysaccharides are large molecules formed by the repetition of simple sugars (monosaccharides) linked together through glycosidic bonds. Common examples of polysaccharides include starch, glycogen, and cellulose, all of which serve important roles in energy storage and structural functions in living organisms.

The other options do not accurately define polysaccharides. A single sugar molecule refers to monosaccharides, which are the basic units of carbohydrates. A chain of amino acids describes proteins rather than carbohydrates. A type of fat molecule pertains to lipids, which are distinct from carbohydrates and do not involve sugar units. Understanding these distinctions is crucial for grasping the basic concepts of nutrition and dietary management.
