Reducing Sugars Purpose: In order to detect the presence of reducing sugars in solution. Hypothesis: When exposed to Benedict’s reagent, reducing sugars will cause the solution to turn reddish-orange brown or green. Null Hypothesis: Benedict’s reagent will cause the same reaction in both reducing and non-reducing sugars. Predictions: 1. If glucose is exposed to Benedict’s reagent then the solution will turn reddish-orange brown. Rationale: 1. Glucose has a free OH group on the anomeric carbon and is therefore able to react with the copper ions in Benedict’s and is therefore a reducing sugar.

Starch Purpose: In order to detect the presence of starch in solution. Hypothesis: When exposed to I 2 KI, starches will cause the solution to turn blue-black. Null Hypothesis: I 2 KI will cause the same reaction in both starch solutions and solutions containing no starch. Predictions: 1. If glucose is exposed to I 2 KI then the solution will remain yellow, the color of I 2 KI. Rationale: 1. Glucose will not turn blue-black because it is not a long, chained, tightly coiled polymer of many glucose molecules. .

Students are responsible for learning the following about each organic molecule: Its monomer (subunit) Its overall structure (what it looks like) The test you used to identify it What a positive test looks like What a negative test looks like Why the test works (what is causing the positive test results) The function of the molecule in the cell.
