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

a molecule made by the joining of two molecules of the same kind, i.e. two MONOMERS. Ultraviolet light can induce THYMINE DIMERS in DNA.

Therefore, the donor action of the non-ligand electronic pairs of the water molecule must decrease the electronic deficiency of MB, decreasing the repulsion between the monomers, which favors the dimerization process.
POU1F1 contains a POU DNA-binding domain with two regions: a POU homeodomain required for DNA binding and a POU-specific domain essential for DNA-binding specificity and dimerization (Ozmen et al., 2014).
The presence of 50 kDa mTcTXNPx and 46 kDa cTcTXNPx, both in the oxidized form, (8) is not observed in samples treated with mercaptoethanol, (9) which likely prevents the formation of disulphide bonds and therefore prevents dimerization.
In this experiment, to ensure equal ligand treatment, the activities were shown by firefly luciferase activities standardized against Renilla luciferase activities for the internal control pRL-tk plasmid and the HepG2 cell line was used because it lacks the nuclear receptor CAR but expresses its dimerization partner RXR, which is involved in recognition of the responsive element in the regulatory regions of genes (Peacock, 2005).
The dimerization of 1-butene is an undesired side reaction that depends on the molar ratio.
Its magnetic moment of 1.53 BM is indicative of an antiferromagnetic spin-spin interaction through molecular association with possible Cu-Cu interaction or dimerization [55].
