Furthermore, besides the existing metabolomic database that can be used for an encyclopedia of metabolites, such as the KNApSAcK, Golm Metabolite Database ([60], http://csbdb.mpimp-golm.mpg.de/csbdb/gmd/gmd.html), and MoToDB ([70], http://appliedbioinformatics.wur.nl/moto/), more metabolomic databases of other plants including rice should hopefully become available.
This local compound database covers structures from the 13 most important metabolomic databases, including BMDB, CheBI, DrugBank, ECMDB, FoodDB, HMDB, KNApSack, PlantCyc, SMPDB, T3DB, UNPD, YMDB and STOFF-IDENT [22], containing 220,213 entries sorted according to InChIKey, PubChem, exact mass, formula and SMILES.
In addition to generating MS/MS data for metabolites included in databases, it is possible to reliably generate MS/MS data on biological peaks which currently cannot be annotated by metabolomic databases.
Using existing database search algorithms and rapidly growing NMR metabolomic databases, it is straightforward using HATS-PR not only to compare biological states but also to identify and assign the relevant compounds that differentiate these states.
We were also able to reassess the performance of the previously used metabolomic platforms (NMR, GC-MS, UPLC-MS) as well as two more metabolomic platforms (DFI-MS/MS and ICP-MS) with regard to their efficacy in CSF metabolite characterization.
Now they know to establish more secure databases.
While both LTH and IR29 showed the similar change patterns for the three major groups of the primary metabolites, LTH showed more dramatic metabolomic responses to the chilling stress than chilling sensitive IR29, reflected by more metabolites showing chilling induced changes, by greater levels of these metabolomic changes, and by a much greater recovery ability after stress.
However, we hypothesized that the multifarious nature of metabolites present in human feces dictates the use of several diverse SPME fiber coatings for more comprehensive metabolomic coverage.

More recent metabolomic studies now suggest that enhanced fat metabolism, as seen with high fat feeding, leads to β-oxidation products that exceed mitochondrial capacity restricting the ability to switch to glucose oxidation [25].
More general metabolomic perturbations were observed in the non-stressed mutant plants.
