Distribution of polar lipids in C. albicans biofilms and planktonic cells: lipidomics analysis of phospholipids in biofilms and planktonic cells grown to (a) early phase (6 h) or (b) mature phase (48 h). PC, phosphatidylcholine; PE, phosphatidylethanolamine; PI, phosphatidylinositol; PS, phosphatidylserine; PA, phosphatidic acid; PG, phosphatidylglycerol; LPC, lyso-PC; LPE, lyso-PE. Data represent mean±se (n = 5). P-values represent comparisons between biofilm and planktonic cells.
