Polymer vs. Macromolecule: Know the Difference
By Shumaila Saeed || Published on January 11, 2024
Polymers are large molecules composed of repeated subunits, while macromolecules are any large molecules, including polymers.
Key Differences
Polymers are substances whose molecules have a high molar mass and are composed of a large number of repeating units. Macromolecules, on the other hand, refer to any large molecule, irrespective of its composition and structure. While all polymers are macromolecules, not all macromolecules are polymers.

The term polymer specifically refers to the chemical structure where small units, monomers, link together. Macromolecules can be polymers, but they also include other large biological molecules like proteins, which are not polymers in a strict sense. Thus, macromolecules encompass a broader range of substances.

Polymers can be naturally occurring, like cellulose in plants, or synthetic, such as plastic. Macromolecules include DNA, proteins, and polysaccharides, along with synthetic polymers. The distinction lies in the diversity of macromolecules, which include but are not limited to polymers.

The synthesis of polymers involves chemical reactions that link monomers. Macromolecules, particularly those in biological systems, are formed through various processes, including polymerization. The formation process of macromolecules can be more complex than that of polymers.

In terms of functionality, polymers are often recognized for their structural and material properties, like elasticity in rubber. Macromolecules, especially in biology, have functional roles such as information storage (DNA) or catalysis (enzymes), demonstrating their diverse nature.
