DIGESTION AND ABSORPTION OF CARBOHYDRATES 193 4. Fiber in food is not enzymatically digested in the digestive tract, because humans don’t have enzymes to do this. However, some dietary fiber is fermented in the large intestine by gut microbes. Carbohydrates in food Is this carbohydrate enzymatically digested? (enzyme name) What is absorbed into the villi after digestion? Monosaccharides Glucose No Glucose Fructose No Fructose. It is then transported to the liver where it is converted to glucose. Galactose No Galactose. It is then transported to the liver where it is converted to glucose. Disaccharides Maltose Yes (maltase) Glucose Sucrose Yes (sucrase) Glucose, Fructose Lactose Yes (lactase) Glucose, Galactose Polysaccharides Starch Fiber Yes (amylase, maltase) No (Humans don’t have the digestive enzymes to break down fiber, but some is fermented by gut microbes in the large intestine.)
