BpForms and BcForms: A toolkit for concretely describing non-canonical polymers and complexes to facilitate global biochemical networks

Non-canonical residues, caps, crosslinks, and nicks are important to many functions of DNAs, RNAs, proteins, and complexes. However, we do not fully understand how networks of such non-canonical macromolecules generate behavior. One barrier is our limited formats for describing macromolecules.
