dimer

 
1. a compound formed by combination of two identical simpler molecules.
2. a capsomer having two structural subunits.
D-dimer a fragment of fibrin that is formed as a result of fibrin degradation. A positive test for its presence in the blood is suggestive of conditions such as thrombotic disease, sickle cell crisis, malignancy, disseminated intravascular coagulation, or recent surgery.

di·mer

(dī'mĕr),
A compound or unit produced by the combination of two like molecules; in the strictest sense, this occurs without the loss of atoms (thus, nitrogen tetroxide, N2O4, is the dimer of nitrogen dioxide, NO2), but usually by elimination of H2O or a similar small molecule between the two (for example, a disaccharide), or by simple noncovalent association (as of two identical protein molecules); higher orders of complexity are called trimers, tetramers, oligomers, and polymers.
[G. di-, two, + -mer]

dimer

[dī′mər]
Etymology: Gk, di, twice, meros, parts
a compound formed by the union of two radicals or two molecules of a single simpler compound.
