Fig. 2

A An example muropeptide showcasing several modifications (yellow) and peptide branches (red). B The same muropeptide converted to its chemical graph representation. Free functional groups (those that remain unmodified and unbonded) are shown as black dots on each residue, bonds are shown as labelled arrows pointing from donor to acceptor, and modifications are shown as yellow flags. C The five functional groups of N-Acetylmuramic acid are shown in detail, including the modifications each can have and the bonds they can donate/accept.
