What is a Monomer?

what is a monomer?
Introduction:
A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins. Monomers bind to other monomers to form repeating chain molecules through a process known as polymerization. Monomers may be either natural or synthetic in origin. Oligomers are polymers consisting of a small number (typically under 100) of monomer subunits. Monomeric proteins are protein molecules that combine to form multi-protein complexes. Biopolymers are polymers consisting of organic monomers found in living organisms.
Examples:
Glucose, vinyl chloride, amino acids, and ethylene are examples of monomers. Each monomer may link in different ways to form a variety of polymers. In the case of glucose, for example, glycosidic bonds may link sugar monomers to form such polymers as glycogen, starch, and cellulose.
Small Monomers:
- Dimer: Polymer consisting of two monomers
- Trimer: Three monomer units
- Tetramer: Four monomer units
- Pentamer: Five monomer units
- Hexamer: Six monomer units
- Heptamer: Seven monomer units
- Octamer: Eight monomer units
- Nonamer: Nine monomer units
- Decamer: 10 monomer units
- Dodecamer: 12 monomer units
- Eicosamer: 20 monomer units
