Note: Results are means ± SEM and are expressed as percents of the total fatty acid content of brain phospholipids. Distinct and similar superscript letters (a, b and/or c) within a same horizontal line indicate significant (p<0.01) and not significant differences between dietary groups towards the considered fatty acid, respectively. The absence of a superscript letter throughout a horizontal line means that no significant difference between the four diet groups occurs in the levels of the considered fatty acid. Abbreviations are : LA, linoleic acid; ARA, arachidonic acid; DPAn-6, docosapentaenoic acid of the n-6 series; ALA, alpha-linolenic acid; EPA, eicosapentanoic acid; DPAn-3, docosapentaenoic acid of the n-3 series, DHA, docosahexaenoic acid. Diets have been defined in the text and in Table 1 and have been given to mice for a period 30 days before analyses of brain phospholipids. Contents in phospholipid saturated fatty acids are 100% from which are withdrawn percentages of phospholipid unsaturated fatty acids given in the table.
