Functions of carbohydrates

Functions of carbohydrates:-

1. They are the most abundant dietary source of energy (4Cal/g) for all

organisms.

2. Carbohydrates are precursors for many organic compounds (fats, amino

acids).

3. Carbohydrates (as glycoproteins and glycolipids) participate in the structure of

cell membrane and cellular functions such as cell growth, adhesion and

fertilization.

4. They are structural components of many organisms. These include the fiber

(cellulose) of plants, exoskeleton of some insects and the cell wall of

microorganisms.

5. Carbohydrates also serve as the storage form of energy (glycogen) to meet the

immediate energy demands of the body.
