Jerell's iPod

     Today in class we started off by discussing macromolecules, hydrolysis, monosaccharides, like glucose, galactose and fructose, disaccharides, like sucrose, maltose and lactose and polysaccharides, like starch. We used this knowledge in our lab, in which we had to determine who had stolen Jerell's ipod based off the food evidence left at the scene. We began by testing known by testing basic substances, such as proteins, starches, and lipids. After this we tested basic foods, like pretzels, beans, jelly and butter. Then we tested both liquid and dry evidence found at the scene and compared our results to what each of the suspects had for lunch. We used the following substances to test for a reaction:
1) Iodine -  tested for starch
2) Benedrict's - tested for glucose
3) Biuret - tested for protein
4) Sudan III - tested for lipids
