A macromolecule is a large molecule (high molecular mass) composed of several smaller subunits called monomers.
Macromolecules are part of the cell of living beings and have vitally important functions. Within their classification are organic (such as proteins) and inorganic (such as the Diamond). In turn, they can be linear (when monomers can be joined by only two places) or branched (when monomers can be joined by more than two places).
On the other hand, there are also natural (originated in nature) or synthetic (synthesized by humans in laboratories) macromolecules. For example, plastic or synthetic fibers and natural proteins.

Composite (also called hetero-proteins)
- Nucleic acids (DNA and RNA)
- Starch (Polysaccharides)
- Glycogen (Polysaccharides)
- Lignin (component of wood)
- B12 vitamin
- Carbohydrates (carbohydrates)
