This experiment was meant to teach us the four kinds of macromolecules: proteins, lipids, carbohydrates, and nucleic acids we are to perform 4 tests which will determine. Describe the differences between an atom and a molecule construct simple molecules from atoms recognize that the subscript in the molecular formula indicates the number of that atom in the molecule recognize that the coefficient indicates the total number of molecules associate common molecule. In doing the lab, one was able to determine the characteristics of the given solutions, containing different macromolecules, whilst doing the multiple tests the tests performed were, iodine testing for starch and glycogen, benedict's test for reducing sugars, and the biuret's test for protein. In this lesson students will complete a lab using indicators to determine which foods contain carbohydrates, lipids, proteins, and/or starches the lab includes pre-lab questions, discussion, lab experimentation, post lab questions, results and conclusion.
