Monomer

Definition

A monomer is a small, simple organic molecule that can join together with other similar molecules to form a polymer. Monomers are the building blocks of larger biomolecules such as proteins, nucleic acids, and polysaccharides.

5 Must Know Facts For Your Next Test

1. Monomers can undergo polymerization to form complex structures like proteins and nucleic acids.
2. Amino acids are the monomers of proteins, while nucleotides are the monomers of nucleic acids.
3. Glucose is an example of a monomer that forms polysaccharides like starch and cellulose.
4. Monomers contain functional groups that allow them to react and bond with other monomers.
5. In biological systems, enzymes often facilitate the polymerization of monomers.
