Dimer

The dimer, a fascinating concept in the world of molecular biology and chemistry, is a special oligomer that comes into existence through the assembly of two monomers, a process known as dimerisation. This union of two monomers leads to a structural arrangement that is typically more stable than the individual monomers alone.

The dynamics of dimer formation are remarkable, as it can take a variety of forms. Homodimers, which consist of two identical monomers, and heterodimers, which are composed of different monomers, are two fundamental categories of dimers. This diversity enables dimers to fulfil a wide range of functions in biological systems, from structural support to regulatory mechanisms.
