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).

  Example :

  Action	Input	Output
  Clear Stereo (clearstereo)
  Clear Tetrahedral Stereo (clearstereo:chirality)
  Clear Double bond Stereo (clearstereo:doublebond)
  Clear tetrahedral wiggly bonds (clearstereo:singleupordownbond)
