A mixture of lipids is applied to a silica gel column

Reference no: EM13257796

A mixture of lipids is applied to a silica gel column, and the column is then washed with increasingly polar solvents. The mixture consists of phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, cholesteryl palmitate (a sterol ester), sphingomyelin, palmitate, n-tetradecanol (tetradecyl = 14), triacylglycerol, and cholesterol. In what order do you expect the lipids to elute from the column? Explain your reasoning. (Notes: Assume neutral pH, some lipids could elute together, look at the structures)
