Cholesterol Modifies Nutritional Values and Flavor Qualities in Female Swimming Crab (Portunus trituberculatus)

Figure 2

Effects of dietary cholesterol levels on fatty acid metabolism of female swimming crab. (a and b) Stacked area chart of fatty acid profiles in hepatopancreas and muscle; (c and e) SFA, MUFA, n-6PUFA, and n-3 LC-PUFA contents in hepatopancreas and muscle (mg/g dry matter); (d and f) relative expression of genes involved in LC-PUFA biosynthesis in hepatopancreas and muscle of female swimming crab; (g and h) heat map of multidimensional correlation between fatty acid contents and LC-PUFA biosynthesis-related gene expression levels in hepatopancreas and muscle. The existence of “” indicates a significant difference between the two comparisons. Data are reported as the mean and SEM of four replicates. Columns represent means with bars indicating standard error. Values within the same row with different superscripts are significantly different . SFA, saturated fatty acids; MUFA, monounsaturated fatty acids; n-6 PUFA, n-6 polyunsaturated fatty acids; n-3 LC-PUFA, n-3 long-chain polyunsaturated fatty acids; fad2, fatty acyl desaturase 2; elovl, elongase; elovl4, elongase 4.
