Today you will see two additional chemical tests for protein (Biurets Test) and fat (Sudan IV Test). Focused Question: Which organic molecules are present in each of the foods tested? Directions: Go to the website:  HYPERLINK "http://www.occc.edu/biologylabs/Documents/Organic%20Compounds/Organic%20Compounds.htm" http://www.occc.edu/biologylabs/Documents/Organic%20Compounds/Organic%20Compounds.htm and complete the online activity. You will test six food substances for the presence of starch, monosaccharides, proteins, and fat. Test results are only valid if the molecule is available to the testing chemical. In most cases it is useful to macerate the food substances in an appropriate solvent, like water. Heating is also sometimes necessary. The teacher has used these methods to prepare the foods. Before you begin, you should design a data table to include both raw data and interpreted data for all the foods you will test. Some things to consider before you begin: What is the raw data in this lab? What is the interpreted data? How many trials (repetitions) of each test would you do if you actually did the lab? What value do you gain by consulting with another person on interpretation of the raw data? Assignment: Individually design a data table to include both raw data and interpreted data for the six foods on the online activity. Complete the online activity. Write a conclusion in which you answer the question (see above) in terms of the foods that you tested. Discuss carefully: what cannot be concluded because of the limitations of the website activity? How do the two tests for fats differ from each other (see back of sheet)? Which do you think would give you better test results? Write an evaluation in which you discuss the following: what are the advantages of completing the tests yourself in the lab rather than doing the online activity? What problems might you anticipate were you to do the actual lab? Second Fat Test: You can find out if a food contains fat by rubbing it on a piece of brown paper bag. If the food contains quite a bit of fat, a translucent spot will appear where you have rubbed. (Translucent means that light will pass through the spot, but you wont' be able to see objects through the spot.) Water in food will also produce a translucent spot, but a water spot will disappear when the water dries.
