Polysaccharides are formed from which of the following?

Polysaccharides are long-chain carbohydrates composed of many monosaccharide units linked together through glycosidic bonds. Monosaccharides, such as glucose and fructose, serve as the building blocks for more complex carbohydrate molecules. When multiple monosaccharides undergo dehydration synthesis (a reaction that removes a water molecule), they form disaccharides or polysaccharides.

For instance, when many glucose molecules join together, they can create starch or cellulose, which are common types of polysaccharides. This process is essential for storing energy and providing structural support in various organisms, highlighting the critical role that monosaccharides play in forming these larger carbohydrates.
