Interpretation of positive-and negative-ion electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) mass spectra of 10-formyl-7,8-dihydrofolic acid (10-FDHFA) and 5-formyl-5,6,7,8-tetrahydropteroic acid (5-FTHPA) is discussed. ESI mass spectra enable unambiguous molecular w
## Abstract [^3^H] 5,10βdideazaβ5,6,7,8βtetrahydrofolate, DDATHF, was obtained by a two step process. First, 2n[^3^H~2~O] was produced in the reaction flask containing m[^1^HAc] by the reduction of n[PtO~2~] with ^3^H~2~, so that a 1[^3^H^+^]:18[^3^H^+^ + ^1^H^+^] ratio of solvent protic species in
