New operator for SMILES. The '>' separates the molecules into groups, based on their role in the reaction (eg. reactant, agent, or product).

  • All parts are optional. ('>>' is a valid reaction)

  • Each component in a reaction has a role:

  • Reactant - starting material(s).

    Agent - molecule which do not contribute or accept atoms to the overall reaction (catalyst, solvent, etc.)

    Product - final result(s).
