... through natural process. Monomers of all classes of macromolecules form larger molecules by dehydration synthesis, a chemical reaction in which one monomer donates a hydroxyl and the other a hydrogen, thus forming a water molecule. A polymer's properties depend on its size, it monomers, the strength of its bonds, and whether links form between different parts of the molecule. Synthetic polymers include the plastics polystyrene ... different kinds of nitrogenous bases. Lipids make up the most structurally heterogeneous class of macromolecules, but all share the property of being wholly o...
