What are the functions for carbohydates?

Carbohydrates serve several essential functions in the body, primarily as a primary energy source. They are broken down into glucose, which fuels cellular activities and supports metabolism. Additionally, carbohydrates play a role in the structural integrity of cells and tissues, such as in the formation of cell walls in plants. They also aid in the storage of energy, with glycogen being the stored form in animals and starch in plants.
