Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Polymers are chains with an unspecified number of monomeric units. a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.
