The managing director of a well-known company on Wall Street thrives on a diet of fruit jam, bread, pasta, and coffee. She exercises intermittently. One day she decides to go to her primary healthcare provider for a routine checkup. The healthcare provider recommends that she take the Benedict's test. Assume that the glucose levels of the patient are high.
Based on your understanding about this scenario, respond to the following:
State the results that the test would indicate (specify the color of the solution).
State the composition and the properties of the ketohexose derived from fruit jam.
Describe the manner in which ketohexose acts as a reducing sugar in the test.
