1.1. Absorption

1.1.1. FATS

1.1.2. PROTEINS

1.1.3. CARBOHYDRATES major once are starch (polysaccharide), lactose (disaccharide),sucrose(disaccharide). The digestive process convert all of these to monosaccharides by hydrolysis glycosidic bonds between the sugars

1.1.3.1. 1. Digestion begins in the mouth salivary gland release a-amlylase ( inactivated by acidity of stomach) -> converts starch into smaller polysaccharides a-dextrines
