Following are the functions of carbohydrates, as mentioned below.
- Energy production: Producing energy and supplying the same to human body cells is one of the major functions of carbohydrates.
- Energy storage: If a human body already possesses enough energy to support all its functions, the excess glucose gets stored as glycogen (most of which is stored in the liver and muscles). This is another function of carbs.
- Build macromolecules: Most absorbed glucose helps in the production of energy. However, some of them get converted to deoxyribose and ribose. These are essential building blocks of essential macromolecules, like DNA, ATP and RNA.
Glucose gets used additionally to produce NADPH molecules, which helps in the protection against oxidative stress. If the entire glycogen storing capacity, energy, glycogen-storing and building needs of a body are met, the excess glucose gets used to make fat. Hence, a diet high in carbs may also lead to weight gain.
Thus, carbohydrates are of immense importance to the human body. An excessive amount of the same can be harmful. Consequently, it would help if you plan a diet in such a way that it contains optimum levels of carbs, which is beneficial for your health.
