Figure 3: Selected representative parameters describing fatty acid profile of erythrocyte membrane phospholipids: ratio saturated/monounsaturated fatty acids (a), ratio ω6/ω3 polyunsaturated fatty acids (b), ω6-arachidonic acid percent of total FA content of phospholipids (c), and ω-3 eicosapentaenoic acid % of total FA content of phospholipids (d), in the groups of obese patients with metabolic syndrome (OB w.MetS, ) and without metabolic syndrome (OB w.o.MetS, ) and of control healthy subjects (CTR, ). Values are represented as mean (□), standard error of the mean (upper and lower limits of the box), and 1.96 × standard error (upper and lower whiskers). Intergroup significant differences () are indicated in each panel. Abbreviations: SAT (saturated fatty acids); MUFA (monounsaturated fatty acids); PUFA (polyunsaturated fatty acids); C20:4 (arachidonic acid); C20:5 (eicosapentaenoic acid); and RBC (red blood cells). Techniques: gas chromatography-mass spectrometry with selected ion monitoring (a–d).
