Feb 19 2014 3:15PM	Normal	Acknowledged	Hi, The depiction of this compound shows the zwitterionic form but this is not reflected in the SMILES string. Is this intentional? If it isn't maybe it can be corrected. Many thanks, Stefan ChemSpider does not distinguish between the Zwiterionic or non-charge separated forms of the structure in such cases, therefore the SMILES is valid for this record whether it explicitly describes the zwiterionic representation or the non-charge separated representation. Thank you for you comment.
