Question : Making use of the tests for carbohydrates outlined in experiment number (5 and 6), design your own scheme for the identification of different classes of carbohydrates (eg: Mono, di, polysaccharides). Starch, Sucrose, Galactose, Glucose, Fructose, Pentose, Lactose, Maltose Test Reagents Positive results Indication Distilled water Formation of precipitate or cloudiness. Differentiate between mono/disaccharides & polysaccharides Solubility Appearance of reddish-brown colour Differentiate between starch and glycogen (branching effect) Differentiate between reducing& non-reducing sugars. Differentiate between reducing& non-reducing sugars. General...
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...

please fill out chart and answer applicable questions attached for thumbs up Part 1: Characterization of carbohydrates with and without digestion by enzymes (You can refer to the complete Lab Procedure which is posted separately for more information about this part of the lab.) You are given a set of samples: starch, sucrose, and glucose. The samples are tested before and after different enzymes are added. After the enzymes are added, the samples are incubated in a 37°C water bath...
