Here's why:
* Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen.
* Monosaccharides are the simplest carbohydrates, like glucose and fructose.
* Disaccharides are formed when two monosaccharides bond together, like sucrose (table sugar).
* Polysaccharides are complex carbohydrates formed by the bonding of many (hundreds or even thousands) monosaccharides.
Some common examples of polysaccharides include:
* Starch: A storage form of glucose in plants.
* Glycogen: A storage form of glucose in animals.
* Cellulose: A structural component of plant cell walls.
* Chitin: A structural component of the exoskeletons of insects and crustaceans.
