MS Comments: | A volume of 1 μL of sample was injected splitless with an inlet temperature of 280 oC into the GC (7890, Agilent)/MS (5975C, Agilent) instrument. Metabolites were resolved by separation on DB-5MS+DG (30 m x 250 µm x 0.25 µm) capillary column (Agilent J&W, Santa Clara, CA, USA). Helium was used as the carrier gas with a flow rate such that myristic-d27 acid eluted at approximately 18 min. The quadrupole was set at 150 ˚C, the source was at 230 °C and the GC/MS interface was at 320 ˚C. The oven program started at 60 ˚C held for 1 min, then increased at a rate of 10 ˚C/min until 320 ˚C. Bake-out was at 320 ˚C for 9 min. Metabolites were ionized by electron impact at 70 eV. All samples were injected three times: twice using scan (50-1000 m/z) mode (1x and 25x dilution for steady-state samples or 1x and 24x dilution for tracer samples) and once using selected ion monitoring (SIM) mode. All of the metabolites described in this study were validated against authentic standards confirming mass spectra and retention times. Integration of ion intensities was accomplished using Mass Hunter Quant (Agilent). Generally, M-57+. Ions (and isotopes) were analyzed. Mass isotopomer distribution analysis was carried out using in-house software using an in-house algorithm adapted from Nanchen et al as previously described. |
