Muscle and other body cells can also use glucose for energy, although fat is often used for this purpose. Complex carbohydrates are long chains of simple sugars that can be unbranched or branched. 7. Isomalt is a polyol produced from sucrose, often used in confectionery. Depending on the type, a gram of carbohydrates provides different amounts of energy: Monosaccharides are directly absorbed by the small intestine into the bloodstream, where they are transported to the cells in need.
