oup e i ent i S caPapie to act as n veducin s enown 6. Draw the ring structures for (-D-fructose and for e-bsfructoseS 7. An unknown carbohydrate gave a red precipitate when tested with Fehling's reagent, turned red when reacted with Seliwanoff's reagent, and quickly gave a red precipitate when reacted with Barfoed's reagent. What conclusions can be made about this carbohydrate? 9. What test could be used to differentiate between sucrose and lactose? Explain.

PRE-LABORATORY ASSIGNMENT Carbohydrates 1. Draw the structures of fructose (ring structures) present in a solution at equilibrium. 2. An unknown carbohydrate showed a positive test reaction when tested with Fehling's reagent, turned red when reacted with Seliwanoff's reagent, and reacted quickly with Barfoed's reagent. What conclusions can be made about this compound? 3. What test could be used to differentiate between the compounds in each set? a. sucrose and maltose b. fructose and glucose c. lactose and glucose

General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....
