Hi all,
I'm adding reactions to a model and noticed that in the model, the chemical formulas do not match those by kegg. Ill provide an example, eg...
M_cpb_m ; Carbamoyl phosphate, charged formula =
CH2NO5P, charge = -2.
The same metabolite in KEGG, (C00169) has a formula of CH4NO5P, so there is a discrepancy of 2 hydrogens.
Does this difference result from the meaning of 'charged formula' and the two missing hydrogens then result in the charge being -2 ?
Is this standard procedure for reporting formulas?
