Clear Stereo¶
This action clears stereo features of molecule. By default, both tetrahedral and double bond stereo information are cleared.
To clear specific stereo type, select:
- Tetrahedral stereo: tetrahedral stereo features ( R , S , and enchanced stereo features as well) are removed, thus racemizing the compounds. (
clearstereo:chirality)
- Double bond stereo: stereo configurations of double bonds are cleared. (
clearstereo:doublebond)
- Convert tetrahedral up-or-down bonds (wiggly) to single bonds: Undefined tetrahedral stereo centers can be marked by using "Single UP or DOWN" bonds (aka wiggly bonds); These bonds will be converted to single bonds by using this option (
clearstereo:singleupordownbond).
