A macromolecule is a very large molecule, usually consisting of repeated subunits called monomers, which cannot be reduced to simpler constituents without sacrificing the building block elementwhile there is no standard definition of how large a molecule must be to earn the macro prefix, they generally have, at a minimum, thousands of atoms. The experiment performed was designed to identify the biological macromolecules these biological macromolecules are to be identified by the changes in colour through three different tests - iodine test for starch and glycogen, benedict's test for reducing sugars, and biuret test for proteins.
Students will be able to identify the structure and functions of the four main types of macromolecules the students will use laboratory testing to determine the identity of an unknown they will fill in a chart about the structures, functions, and examples for each macromolecule type and then they will practice their knowledge by answering.
