What is a dimer ?

A dimer is a molecule composed of two smaller, identical molecules (monomers) that are chemically bonded together. The process of forming a dimer is called dimerization. Dimerization can occur in various types of molecules, including proteins, nucleic acids, and organic compounds.

A dimer is a molecule that consists of two identical subunits linked together. The subunits can be atoms, molecules, or ions. Dimers are often formed by the covalent bonding of two molecules, but they can also be formed by other types of interactions, such as hydrogen bonding or van der Waals forces.

Dimers are often more stable than the individual subunits, because the interactions between the subunits help to hold the molecule together. Dimers can also have different properties than the individual subunits, such as different solubility or reactivity.

Dimers are found in a wide variety of chemical systems, including organic compounds, inorganic compounds, and biological molecules. For example, water is a dimer of hydrogen oxide, and DNA is a dimer of nucleotides.
