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.
Two types of complex carbohydrates are particularly important for nutrition: 1  Starch: Starch is a polysaccharide that plants use to store energy. 2  Dietary Fiber: Dietary fiber is found in plants as cellulose, pectin, and lignin.imple carbohydrates are composed of single-unit sugars called monosaccharides and disaccharides. Glucose and fructose are examples of common monosaccharides. Simple carbohydrates are easily digested and converted to sugar rapidly in the bloodstream.
