Exploring Carbohydrates

Carbohydrates are essential organic compounds made of carbon, hydrogen, and oxygen. They play a crucial role in providing structure to organisms, such as cellulose in plant cells and shells of crustaceans. Carbohydrates are also vital for energy supply and storage, as they are digested to fuel the body and stored as glycogen. Foods rich in carbohydrates include starches, grains, and sugars, which vary in type and amount. Carbohydrates are multifaceted molecules that are indispensable to life.
