What is a primary function of carbohydrates in the body?

Carbohydrates serve as a primary source of energy for the body. When consumed, they are broken down into glucose, which is then utilized by cells for various energy-requiring processes. This is especially crucial during physical activity where the demand for quick energy increases. Glucose can also be stored in the liver and muscles as glycogen to be used later when the body needs an immediate energy source, such as between meals or during strenuous exercise.

While carbohydrates contribute to other bodily functions, such as providing some structure in certain cells (through polysaccharides) and playing a supportive role in metabolic health, their most recognized and vital role remains as the main energy supplier. This is essential for maintaining overall bodily functions, including brain function, muscular activity, and maintaining metabolic processes.
