Four phospholipids are present in a mixture, with each phospholipid having a different length for its hydrocarbon tails: phosphatidylcholine (pc): composed of c18 lipid tails phosphatidylethanolamine (pe): composed of c16 lipid tails phosphatidylinositol (pi): composed of c12 lipid tails phosphatidylserine (ps): composed of c20 lipid tails if this mixture of phospholipids is resolved on a thin-layer chromatography (tlc) plate, what will be the order of the phospholipids on the plate at the end of the experiment, from closest to the solvent front to closest to the origin? assume that the length of the phospholipid tails is the primary determining factor in the experiment.
