  • Each value represents the mean ± s.d. of the relative proportion of the FA (or UFA/SFA ratio) calculated from phospholipid species composition. The differences between the initial state and the treatments were statistically analyzed using unpaired two-tailed t-tests (*P<0.05; **P<0.001; ***P<0.0001).
