Maltose = glucose + glucose broken down by maltase 2 glucose units. Sucrose = glucose + fructose broken down by sucrase glucose + fructose. Lactose = glucose + galactose broken down by lactase glucose + galactose: all these enzymes are found in the small intestines. 4. 8: hydrolysis reaction: maltose + water broken down by maltase 2 glucose units, we do this during digestion, condensation reaction: 2 glucose units maltose + water (creating bonds) Dri values: 45-65% kcal for carbohydrates, 14 g/1000 kcal for fibre. **it is hard to avoid carbohydrates in your diet they bought low-fat produ(cid:272)ts, (cid:271)ut the(cid:455) did(cid:374)(cid:859)t k(cid:374)o(cid:449) that they were getting more calories from it as more sugar was added.
