Sucrose, or table sugar, is just one type of carbohydrate. Sucrose, glucose and starch are related because they're all forms of carbohydrate. One of the essential macronutrients in foods along with protein and fat, carbohydrates supply energy to your body. Carbohydrates, which consist of carbon, hydrogen and oxygen, are classified according to their chemical makeup.
Carbohydrates provide glucose to the body, stabilizing the body's glucose levels. However, when the body does not have enough carbohydrates, it breaks down protein for that purpose, meaning that protein cannot be used to build muscle. Carbohydrates give energy to muscles and the central nervous system.
