Table 1. How metabolomics data match metabolic models.
| human model | human model (BioCyc) | yeast model (BioCyc) | |
| number of reactions | 4204 | 2091 | 1034 |
| metabolite edges | 18504 | 14100 | 6962 |
| number of metabolites | 3565 | 1536 | 811 |
| number of metabolites with exact mass | 2016 | 1308 | 742 |
| case moDC: reference features | 7713 | 7713 | |
| case moDC: tentatively matched metabolites | 1384 | 874 | |
| case urine: reference features | 10248 | 10248 | |
| case urine: tentatively matched metabolites | 1453 | 930 | |
| case yeast: reference features | 5366 | ||
| case yeast: tentatively matched metabolites | 533 |
The top section gives statistics of each of the three metabolic models. The bottom section gives the specific number of measured features and tentative metabolite matches in each study case. These tentative matches contain excessive ambiguity, which mummichog aims to resolve.
