Membrane unsaturation indexes. The unsaturation index is the sum of the percentages of each FA in a fraction multiplying by the number of the considered fatty acid double bound. SL, sarcolemmal; NU, nuclear; MI, mitochondrial; SR, sarcoplasmic membrane. Data are means ± SEM, n = 6. Dietary effect (CTL versus DHA versus ALA) was compared in rats from the same dietary treatment duration and values with different letters are statistically different, a>b>c, p < 0.01. Time effect (2 months versus 6 months) was compared between rats from the same dietary group, with * = p < 0.05 and *** = p < 0.001.
