Luther found a vial containing an unknown lipid sample. He separatedthe different lipids using gel filtration chromatography anddetermined the identities of the different lipid eluents using normalphase TLC. Help Luther complete the table below. Report thedistance travelled of eluents and solvent in two decimal places andthe Rf in four decimal places. For the identities of the lipids, refer tothe provided pool of chemical structures and write only the lettercode.EluentsDistanceTravelled (cm)RfIdentityEluent A(1)0.5541(5)Eluent B5.90.3758(6)Eluent C13.25(3)(7)Eluent D(2)0.2325(8)Solvent front, cm(4)POOL OF CHEMICAL STRUCTURES:LETTERCODEOFFGUNEARTHMIXHOSTRUCTUREH

A mixture of lipids is applied to a silica gel column (a column chromatography), and the column is then washed with increasingly non-polar solvents. The mixture consists of phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, cholesteryl palmitate (a sterol ester), sphingomyelin, palmitate, n-tetradecanol, triacyglycerol, and cholesterol. In what order will the lipids elute from the column? Explain the reasons for your answer(s).
