Heatmaps of glycerophospholipids and free fatty acids. (A) Heatmap of ethanolamine and phospho-ethanolamine, both detected by GC-TOFMS, and the total amounts of phosphatidylethanolamine (PE), phosphatidylcholines (PC), spingomylins (SM) and triglycerides (TG), all detected by UPLC-MS. (B) Heatmap of 18 free fatty acids, all detected by GC-TOFMS. The fatty acids are annotated by the number of carbon atoms, the number of double bonds and the omega position of the double bonds. The bars at the top of the heatmaps encode the type of tissue: invasive carcinoma (T) = red, normal breast tissue (NB) = dark grey, adipose-rich normal tissue (NA) = light grey.
