 The mcule registration system supports the distinction between unknown and unspecified/undefined cis-trans configurations. Unknown cis-trans configuration represents a structure having either E or Z configuration but definitely one of them. In unspecified/undefined cases the structure can also represent the mixture of the cis and trans isomers. The mcule registration system supports the distinction between unknown and unspecified/undefined cis-trans configurations.

-Although the mcule registration system can distinguish between unknown and unspecified/undefined cases, the currently implemented molecule editor and visualization tools (ChemWriter and ChemVector) don’t provide different bond types for these two configuration types. Unknown and unspecified/undefined cis-trans configurations are therefore both displayed by crossed double bond. If unspecified double bonds are present, we indicate them in the comment field of the compound index pages.+Although the mcule registration system can distinguish between unknown and unspecified/undefined cases, the currently implemented molecule editor and visualization tools (ChemWriter and ChemVector) don’t provide different bond types for these two configuration types.
