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.
While your mouth isnât technically an organ, it is the place where carbohydrate digestion first begins. When you chew, sugar molecules head right down into your digestive tract, but starch compounds need the help of saliva in your mouth. Saliva breaks apart complex starch molecules, making it easier for digestion in your stomach.
