A notable molecule editor is a computer program for creating and modifying representations of chemical structures.
Database molecular editors such as Leatherface,[1] RECAP,[2] and Molecule Slicer[3] allow large numbers of molecules to be modified automatically according to rules such as 'deprotonate carboxylic acids' or 'break exocyclic bonds' that can be specified by a user.
Molecule editors typically support reading and writing at least one file format or line notation.
Examples of each include Molfile and simplified molecular input line entry specification (SMILES), respectively.
Files generated by molecule editors can be displayed by molecular graphics tools.
