Solution

Carbohydrates are a macronutrient whose primary function is to provide energy to the body. All digestible forms of carbohydrates provide 4 calories/g of energy. Fiber, starch and glycogen are complex carbohydrates. Simple carbohydrates can be monosaccharides, like glucose and galactose or disaccharides like lactose and maltose. Complex carbohydrates include polysaccharides.Starch consists of chains of glucose molecules. Some starch chains are straight and harder to to digest. Other starch is much easier to digest and has branching chains.Dietary fiber consists of soluble and insoluble types, which both posses important benefits like reducing the risk of constipation, heart disease,and obesity. Soluble fiber also helps reduce the risk of diabetes. Glycogen is a highly branched polysaccharide created by process called glycogenesis and is stored in liver and musckesfor later use. Carbohydrate in the diet are said spare protein from being used to provide for fuel for the cells.
