cyclisation
Forming molecular rings
Cyclisation is the British spelling of cyclization—a chemical reaction in which a chain of atoms forms a ring, creating a cyclic compound.
The process is fundamental in organic chemistry and biochemistry, appearing in the synthesis of sugars, steroids, and countless pharmaceuticals: The cyclisation of squalene produces cholesterol.
