Molecular network identifying possible connection between SOMA and IOMA. (A) One component that represents 70% of SOMA–IOMA attributions displays a connection between SOMA and IOMA. The gray nodes represent the IOMA attributions. (B) Frequencies related to edges H₂, O, CO, CO₂, and NH₃ are reported and set as SOMA-to-IOMA or IOMA-to-SOMA transitions. (C) SOMA attributions that are directly connected to IOMA ones were extracted and represented as DBE versus #C. These compounds can be considered as direct IOMA precursors.
