2. Fig. 1
Estimated enzyme activities in serum cholesteryl esters according to study groups in the KOBS and METSIM studies. Panels (A) and (C) show mean (±SD) enzyme activities in individuals with normal liver, steatosis and steatohepatitis in obese individuals in the KOBS study (n=92). Panels (B) and (D) show estimated enzyme activities in high ALT group (plasma ALT >24U/l) and in low ALT group (serum ALT ≤24U/l) in the METSIM population study (n=769). Activity of delta-6 desaturase was estimated in CE by a ratio of 18:3 n-6/18:2 n-6 and activity of delta-5 desaturase by a ratio of 20:4 n-6/20:3 n-6. * p<0.002 compared to individuals with normal liver in t test.

3. Fig. 2
Hepatic mRNA expression of desaturase genes and correlations with estimated desaturase activities in serum triglycerides. Bar charts show mean levels (±SD) of mRNA expression in the liver according to study groups based on liver histology: panel (A) for FADS2 and panel (B) for FADS1. Scatter plots show correlations between hepatic mRNA expression and estimated enzyme activity in serum triglycerides for FADS2 and delta-6 desaturase in panel (C) and for FADS1 and delta-5 desaturase in panel (D). Spearman correlation coefficients are shown in the panels C and D, respectively. Activity of delta-6 desaturase was estimated by a ratio of 18:3 n-6/18:2 n-6 and activity of delta-5 desaturase by a ratio of 20:4 n-6/20:3 n-6
*p<0.05 compared to individuals with normal liver in independent samples t test.

4. Fig. 3
Scatter plots demonstrating the correlation between enzyme activities based on liver and serum fatty acid ratios for delta-6 desaturase in cholesteryl esters (A) and triglycerides (C) and for delta-5 desaturase in cholesteryl esters (B) and triglycerides (D). Spearman correlation coefficients are shown in the panels A-D, respectively. Activity of delta-6 desaturase was estimated by a ratio of 18:3 n-6/18:2 n-6 and activity of delta-5 desaturase by a ratio of 20:4 n-6/20:3 n-6.
