(A) Composition of fatty acid species within PC, PE, and PI in OSCC (blue) and healthy (orange) tissue. Fatty acids for each GPL subspecies have been separated by 1) those with <2 double bonds, ≥2 double bonds, etc.; 2) the number of double bonds; 3) chain length and number of double bonds; and 4) chain length. The area of each circle is proportional to the abundance of each fatty acid moiety pmol/mg tissue. Only lipids that are significant after using the Benjamini-Hochberg multiple testing correction are shown with an asterisk.
