What is a monomer

A simple molecule with two or more binding sites is referred to as a monomer. Through these sites, it can establish covalent bonds with other monomer molecules to create a macromolecule.

Thus, monomers serve as the foundation for polymers. Only simple molecules with two or more binding sites can behave as monomers; all other simple molecules cannot. As a result, molecules like ethanol, water, and ammonia are not monomers. As monomers, we have alkenes, vinyl chloride, adipic acid, and glycol with two binding sites.

In essence, monomers serve as building blocks for compounds such as proteins, carbohydrates, and several other polymers. There are four types of large monomers: fatty acids, nucleotides, amino acids, and monosaccharides. These monomers—proteins, nucleic acids, carbohydrates, and lipids—are the primary types of macromolecules.

Why do monomers matter?

Thousands of monomers may make up a polymer, or it may just have a handful. Each monomer that makes up the polymer performs a certain "role" on the team, which has an impact on how the polymer acts, appears, tastes, and smells. The final outcome is also influenced by where the monomer appears in the polymer chain. When one significant monomer is removed, another is added, or their position in the chain is changed, the polymer also changes.

It's crucial to know what monomers are present in your polymer, whether you're working with a natural polymer in the food processing industry or synthesizing a new polymer that you think will revolutionize the oil-refining sector. When creating a new polymer, knowing which monomers go into it will help you get the outcomes you desire. Additionally, monomer analysis can help you understand the potential benefits or drawbacks of a natural polymer as well as any potential contamination by leftover monomers from a synthesis process.
