Lab Report: Macromolecules Macromolecules atomic number 18 large organic molecules that are typically ensnare as polymer chains which are constitute of many monomer subunits. Nucleic acids, proteins, carbohydrates and lipids are all examples of macromolecules commonly found in cells. These are found in all living things. In the experiments we tested organic samples for the presence of nucleic acids, proteins carbohydrates, and lipids. We were given unknown 4, and found on our unknown given our sense observation, besides tastes of strain; we concluded that it was high in sugar. We then decided to have with the sugar test first.
