| Title | Physcomitrella patens metabolite analysis using stable isotopes |
| Description | Metabolites in the Physcomitrella patens are investigated by using stable isotope labelings. This analysis was performed to estimate the elemental composition with high reliability using the number of stable isotopes incorporated in the compound as an index and to add information to discuss the biosynthetic pathway. The Physcomitrella patens were labeled with 13C, 15N, 18O, and 34S, respectively in the same condition. Following peak picking by using PowerGet, the metabolite list was prepared from unlabeled data and blank data. The isotopic peaks were searched and listed using ShiftedIonsFinder. Moreover, the flavonoid-like peaks were also searched using ShiftedIonsFinder. |
