A total of 41 (3.07%) metabolites are not produced by any reaction of the model: 2me4p_c, 2pglyc_c, 4gudbd_c, 5fthf_c, allphn_c, ...

Orphans are metabolites that are only consumed but not produced by reactions in the model. They may indicate the presence of network and knowledge gaps. Implementation: Find orphan metabolites structurally by considering only reaction equations and bounds. FBA is not carried out.

This model contains 626 unconserved metabolites: for_e, pydx_c, mnl1p_c, hisp_c, pydx5p_c, ...

The list of unconserved metabolites is computed using the algorithm described in section 3.2 of "Detection of Stoichiometric Inconsistencies in Biomolecular Models." Bioinformatics 24, no. 19 (2008): 2245. doi: 10.1093/bioinformatics/btn425.
