  1. Values are expressed as relative amounts of the total fatty acid content. The analysis was performed on 5 samples randomly selected in each group. ZL: Zucker lean rats; ZDF: Zucker diabetic fatty rats; DMA: dimethylacetal; SFA: saturated fatty acids; MUFA: monounsaturated fatty acids; PUFA: polyunsaturated fatty acids; EPA: eicosapentanoic acid; AA: arachidonic acid; DHA: docosahexaenoic acid; *: significantly different.
