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...

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...

p. If you accidentally forgot to inoculate your organism in an OF-glucose tube with oil, and only had one yellow “no oil” tube, what type of carbohydrate catabolism would describe that organism (fermenter, oxidative, neither)? Explain your answer. q. What are two other results from the OF-glucose tubes other than their type of carbohydrate catabolism? r. How can organisms that don't use starch grow on a starch agar plate? Carbohydrate Catabolism...
