Introduction: The purpose of this experiment was to isolate and characterize macromolecules. Macromolecules are huge highly organized molecules. These molecules carry out the activities of the cell. There are four major categories in which these molecules can be placed into. These groups include carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are organic molecules that are usually used to store chemical energy and building material for biological construction. Lipids are a group of non-polar molecules whose common property is that they are water insoluble. Proteins are polymers that are built from amino acid monomers. They carry out almost all of the cell's activities. Proteins perform a variety of activities including the acceleration of metabolic reactions, providing of mechanical support to the cell, and have regulatory functions in areas such as hormones, growth factors and gene activators. Nucleic acids are made as long strands called nucleotides. There are two types of nucleic acids, ribonucleic...
