Final answer:
Polysaccharides are complex carbohydrate polymers formed from the linkage of many monosaccharide monomers. Starch, a well-known polysaccharide, is commercially prepared by controlled hydrolysis of starches and serves as a storage form of energy in plants.
Step-by-step explanation:
Polysaccharides are complex carbohydrate polymers formed from the linkage of many monosaccharide monomers. One well-known example of a polysaccharide is starch, which is commercially prepared by controlled hydrolysis of starches. Starch is a storage form of energy in plants and is found in foods such as corn, potatoes, rice, and wheat. When starch is hydrolyzed, it forms glucose, which can be used for energy or stored for later use.
