Procedure II – Group 2: Unknown Sample Solutions
Complete the table below using your data from Procedure II. For each sample solution (A-E) indicate any color change that occurs when a test solution is added. Next, use Data Table I to determine the biomolecule classification for each sample solution. Hint: compare the color changes in both tables to make your determinations.

Observations and Questions
[5] In Procedure II, did any of your unknown sample solutions (A, B, C, D, E) contain sugars? If yes, which one? What information helped you to come to that decision?
[6] In Procedure II, did any of your unknown sample solutions (A, B, C, D, E) contain protein? If yes, which one? What information helped you to come to that decision?
[7] Using the laboratory tests in this experiment, would you be able to distinguish between a small molecule such as amino acid from a larger molecule such as a protein? Explain why or why not.
[8] Using the laboratory tests in this experiment, would you be able to distinguish between a starch and a sugar such as glucose? Explain why or why not.
