Note: Results are means ± SEM and are expressed as percents of the total fatty acid content of erythrocyte membrane phospholipids. Distinct and similar superscript letters (a, b, c and/or d) within a same horizontal line indicate significant (p<0.01) and not significant differences between dietary groups towards the considered fatty acid, respectively. 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 n3 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 erythrocyte membrane phospholipids. Contents in phospholipid saturated fatty acids are 100% from which are withdrawn percentages of phospholipid unsaturated fatty acids given in the table.
