Your body has a mechanism and set of enzymes for digesting the carbs, protein and fat molecules in your food. Chemical digestion occurs in several steps beginning in the mouth and ending with absorption in the small intestinal cells.
Almost all foods have carbohydrates. Carbohydrates are essential for two distinct functions in your body -- energy and digestion. Most types of carbohydrates, such as starch and sugar, break down into glucose, which is the simplest form of carbohydrate and your body's primary source of energy.Fiber, another type of carbohydrate, is vital to normal digestion; however, it does not break down into glucose.ost types of carbohydrates, such as starch and sugar, break down into glucose, which is the simplest form of carbohydrate and your body's primary source of energy.
