  1. The number of experiments was 6 per group. Except for the different ratios, the results are expressed in percent of total fatty acids. The C22:4 n-6/C20:4 n-6 and C16:1 n-7/C16:0 ratios must be multiplied by 10−2. The C20:2 n-6/C18:2 n-6 and C18:3 n-6/C18:2 n-6 ratios must be multiplied by 10−3 and 10−4, respectively. DMA: dimethylacetal; SFA: saturated fatty acids; MUFA: monounsaturated fatty acids; PUFA: polyunsaturated fatty acids; EPA: eicosapentaenoic acid; AA: arachidonic acid; DHA: docosahexaenoic acid. C: control group; HF-: high fat-fed animals without weight gain compared to the control rats; HF+: high fat-fed animals with weight gain compared to the control rats; a, b, c: two means located on a same line without a common letter are significantly different.
