* Carbohydrates: Polysaccharides

* Examples: starch, glycogen, cellulose

* Proteins: Polypeptides (which are made up of amino acids)

* Lipids: Technically, lipids are not considered polymers in the same way as carbohydrates, proteins, and nucleic acids. They are large molecules, but they aren't built by linking together repeating monomers. However, some lipids like triglycerides are formed from the combination of glycerol and fatty acids.

* Nucleic Acids: Polynucleotides

* Examples: DNA, RNA
