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.
How are carbohydrates digested?   Starch digestion begins in the mouth. As food does not remain long in the mouth, only a little starch is digested by salivary amylase to maltose. No digestion of carbohyâ¦drates occurs in the stomach; only proteins are digested in the stomach.
