2 Introduction: The majority of organic compounds in living organisms are either carbohydrates, proteins, lipids, or nucleic acids. Each of these macromolecules are a part of a smaller subunit that are linked by dehydration synthesis. Dehydration synthesis is an energy requiring process where a molecule of water is is removed and the two subunits are bonded covalently. Hydrolysis happens when an additional water molecule is added in order to break a bond between subunits. Controlled experiments are tests that involve two or more treatments: an unknown solution that will be identified in the experiment and a controlled solution for comparison. A positive control contains the variable being tested. A positive control shows what a positive test should look like. A negative control does not contains the variable trying to be found in the experiment. The negative control is usually distilled solute with no water and won't react in the test. A negative control shows what a negative test should look like. Once these two variables are obtained the experiment can proceed to compare the other variables to the positive and negative controls. The hypothesis is that the tube with the most x substance will be closest in color to the positive control. Materials: 1. Test tubes 2. Hot plate 3. Beaker 4. Distilled water 5. Benedict’s solution 6. Pipet dropper 7. Iodine 8. Onion Juice 9. Potato juice 10. Sucrose solution 11. Glucose solution 12. Starch solution

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
