Global lipidomic profiling of plasma (PL), bone marrow (BM), and bone powder (BP) samples obtained from investigated mice using LC-MS. Heatmap of the sum of the abundances of unique lipid species for each lipid class for (a) plasma, (b) bone marrow, and (c) bone powder with group averages (n = 5-10 per group). Lipid classes statistically altered are marked by an asterisk (*) based on ANOVA with p(FDR) < 0.05. Differences between groups are marked as 1 (ND vs. HFD; p < 0.05), 2 (ND vs. HFD + F; p < 0.05), and 3 (HFD vs. HFD + F; p < 0.05) (gradient color keys used in normalized intensity, A.U.).
