What are carbohydrates primarily known for?

Carbohydrates are primarily known for being the body's main source of energy. This macronutrient is crucial for fueling the body's cells, tissues, and organs. When consumed, carbohydrates are broken down into glucose, which is then utilized by the body for immediate energy needs or stored for later use in the form of glycogen in the liver and muscles. This energy is essential for various bodily functions, including physical activities, brain function, and overall metabolic processes.

Other options involve aspects that do not primarily define carbohydrates. Healthy fats are associated with a different macronutrient group, proteins are formed from amino acids rather than carbohydrates, and while carbohydrates can enhance flavor through foods like fruits and grains, their main role is energy provision rather than flavor enhancement.
