Definition of closed chain in English:
A number of atoms bonded together to form a closed loop in a molecule.
- A ring compound, also called a cyclic compound, is one whose molecules contain atoms chemically bonded together to create a closed chain or circle.
- In general, these two closed chains are linked catenanes, and the type of linkage reflects a topological property of the original substrate.
- A phantom chain utilized in numerical simulations of polymers can explore all subspaces, whereas a real closed chain forming a figure-of-eight knot, for example, is confined to a subspace corresponding to this knot type only.
