Macromolecules (also known as supermolecules) are commonly grouped into four major categories: proteins, nucleic acids, lipids and carbohydrates. These are mainly composed of polymers, long molecules made up of a large number of small, similar molecules, or monomers. Proteins are polymers of amino acids. Long amino acid chains are folded into complex shapes, the shape of each determining the function of the protein.
