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
