Glucose and starch are two types of carbohydrates. Carbohydrates (except cellulose) are broken down in the body to the simple sugar, glucose. As you will recall, glucose is part of the cellular respiration reaction that occurs in every cell of the body. In the laboratory, we can test for the presence of these two carbohydrates by using two different chemical tests. Before we begin to test actual foods, we need to find out what visible effect occurs when we conduct these tests. Therefore, we will do the following:
 * Testing for Glucose and Starch ** (Experiments 5.1 and 5.2; pg 107)


 * Add water, glucose and starch solutions to 2 test tubes each and record the effects of adding iodine and Benedict's solution to each.
 * After drawing conclusions about the effects of these tests, we can test a variety of foods by following the procedures on pg 107.
 * Record all information in a table in your notebook.
 * Be sure to write up your information __clearly__ and __neatly__ in your book.
