monomer

 [mon´o-mer]
1. a simple molecule of relatively low molecular weight, which is capable of reacting chemically with other molecules to form a dimer, trimer, or polymer.
2. some basic unit of a molecule, either the molecule itself or some structural or functional subunit of it, e.g., an individual polypeptide in a multi-subunit protein.
fibrin monomer the material resulting from the action of thrombin on fibrinogen, which then polymerizes to form the fibrin clot.

mon·o·mer

(mon'ō-mĕr),
1. The molecular unit that, by repetition, constitutes a large structure or polymer; for example, ethylene, H2C=CH2, is the monomer of polyethylene, H(CH2)nH.
See also: subunit (1).
2. The protein structural unit of a virion capsid.
3. The protein subunit of a protein composed of several loosely associated such units, usually bound noncovalently.
[mono- + -mer]

monomer

A single unit of a multiunit molecule, which are joined to form dimers, trimers and polymers; hydrolysis of polymers yields monomers.
