Table 1. Metabolomic target analysis of key chemical species participating in the one-carbon pool pathway. The separation and quantification was performed as described in the Methods section. The area of the peak (calculated on the basis of appropriate standards) as determined in triplicate assays (with standard deviation) by CE-TOF-MS is given.
