Definition of closed chain in US English:

closed chain


  • A number of atoms bonded together to form a closed loop in a molecule.

    • ‘In general, these two closed chains are linked catenanes, and the type of linkage reflects a topological property of the original substrate.’
    • ‘A ring compound, also called a cyclic compound, is one whose molecules contain atoms chemically bonded together to create a closed chain or circle.’
    • ‘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.’
    • ‘The topology of a closed chain does not change during the large-scale conformational rearrangement-the DNA chain does not break or pass through itself in this process-.’
