Subject - General Chemistry

In general, the term monomer (from the Greek monos, "single" and meros, "part") describes single or basic units which combine to form the much larger macromolecular compound or polymer. Depending on the specific field, the actual meaning varies.

Subject - Biochemistry

In biochemistry, the following biopolymers play an important role: nucleic acids (monomers are nucleotides or the corresponding activated nucleotide triphosphates), proteins (monomers are amino acids) and polysaccharides (monomers are monosaccharides such as glucose and fructose). Additionally, in biochemistry and molecular biology, the sub-units of polymeric proteins are described as monomers.

Subject - Macromolecular Chemistry

In the field of macromolecular chemistry, the term monomer encompasses all compounds which form polymers in a polymerization reaction. These reactions include different reaction types, including additions and condensations, and the monomers can belong to different classes of compounds.
