Foldit Wiki

The Fragment Selection panel with the Unsaturated Cyclic category displayed.

Unsaturated Cyclic is a category of fragments that can be added to a ligand in a Foldit small molecule design puzzle using the Fragment Selection panel.

The unsaturated cyclic category includes fragments with a single ring structure. In this category, the ring atoms have few attached hydrogens. The ring atoms are instead double-bonded as much as possible.

In contrast, the ring atoms in the Saturated Cyclic fragments have more attached hydrogens. The ring atoms in these fragments are shown with single bonds.

The unsaturated cyclic fragments are listed below in the order they appear on the fragment selection panel. The links go to the corresponding wikipedia pages. Due to the number of fragments, scrolling is required to see all the unsaturated cyclics.

See the Unsaturated Cyclic gallery for ball-and-stick models of the unsaturated cyclics available in the Fragment Selection tool.
