DMA, Dimethylacetal; AA, arachidonic acid, 20:4 n-6; DHA, docosahexaenoic acid, 22:6; SFAs, saturated fatty acids; MUFAs, monounsaturated fatty acids; LA, linoleic acid, 18:2 n-6; n-6 DPA, docosapentaenoic acid, 22:5 n-6; n-3 DPA, docosapentaenoic acid, 22:5 n-3. Adolescence to adulthood n-3 deprivation modifies mPFC fatty acid composition. Fatty acid composition in mice fed with n-3-balanced or n-3-deficient diet from PND 28 to PND 90. Results are expressed as percentage of total fatty acids (n = 4).
