    KamasehGbeanquoi LO5 ChemLife - Word w View Tell me what you want to do There are other types of reagents used to determine what type of biomolecule a substance is. For example, copper ions present in Benedict's reagent reacts with the free end of any reducing sugars, such as glucose, when heated. Originally blue in color, these copper ions are reduced by the sugar, and produce an orange-red colored precipitate. Alternatively, iodine-potassium iodide (KI) may also be used when working...
