Lipidomic and flux in liver of mice expressing constitutively active SREBP-1a. A, B: Lipid species determined from 1H NMR spectra of liver. C: Percent contribution of DNL, desaturation, and elongation to liver TG FAs during 1 day of 2H2O exposure. D: Mass of FAs (attached to TGs) derived from DNL, desaturation, or elongation. E: Percent of TG glycerol that was newly made during 2H2O exposure. F: Mass of FAs on new glyceride. Data are presented as the mean ± SE (n = 5). * Different from control (P < 0.05).
