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.
The majority of carbohydrate digestion occurs in the small intestine. It is here that disaccharides (sugars composed of two monosaccharides) like sucrose, maltose, and lactose are broken down into monosaccharides, which are then absorbed directly into the cells that form the intestinal lining.igestion of starch begins in the mouth with the chewing of food (mastication) and the production of amylases immediately breaking down certain starches.
