The chemical structure of a young protostar is an essential input to models predicting how young modern-day equivalents of the solar system nebula may evolve. The article by Jorgensen and collaborators provides a broad SMA molecular line survey of the prototypical low-mass Class 0 protostar IRAS 16293-2422 and allows a useful overview of the chemical composition of this object on a scale of a few hundred AU. It will be essential input for future ALMA studies of this object.
