Table 4 The desaturation indices and the elongation index.

From: Subcutaneous adipose tissue fatty acid desaturation in adults with and without rare adipose disorders

Index Group
  Control (n = 6) DD (n = 6) FML (n = 8) MSL (n = 5)
Desaturation Index     
   palmitoleic/palmitic 0.13 (0.12-0.14) 0.09 (0.08-0.14) 0.11 (0.08-0.13) 0.13 (0.11-0.25)
   oleic/stearic 11.4 (8.5-12.4) 7.8 (6.2-8.5) 8.4 (6.5-9.7) 13.2 (5.8-21.1)
   vaccenic/stearic 0.86 (0.66-1.34) 0.33 (0.22-0.46)*† 0.81 (0.72-1.37) 0.58 (0.38-3.26)
   (palmitoleic+vaccenic)/palmitic 0.27(0.23-0.34) 0.18 (0.15-0.21)†‡ 0.34 (0.27-0.36) 0.37 (0.20-0.43)
Elongation Index     
   stearic/palmitic 0.18 (0.15-0.25) 0.22 (0.20-0.30) 0.24 (0.19-0.27) 0.15 (0.10-0.24)
  1. Fatty acid ratios are presented as the median in arbitrary units with the 25-75% interquartile range in parentheses. DD demonstrates a decrease in the vaccenic/stearic ratio in comparison to Controls and FML
  2. DD Dercum's disease, FML Familial multiple lipomatosis, MSL Multiple symmetric lipomatosis
  3. *p < 0.05 vs. Control; †p < 0.05 vs. FML; ‡ trended lower vs. Control (see text)
