1. Draw the structures of triacylglycerol, cholesterol, phosphatidylcholine, and sphingomyelin. 2. Identify the polar/charged groups and draw how water will orient itself around these groups. 3. Order these lipids from most hydrophobic to most hydrophilic. 4. Predict how the lipids will migrate on the TLC plate when the running buffer is an organic solvent. Keep in mind that although the lipid standards are dissolved in organic solvent, they can (by virtue of their polar/charged groups) interact with the polar silica matrix of the TLC plates.

From the list below, select the statements that are FALSE. (more than one) OThe hydropathy index plot is used to identify hydrophobic patches inside the cell membrane's architecture. The GPI anchor is a special biomolecule linking a protein to the cell membrane. The phosphoglycerides of the cell membrane contain only saturated or monounsaturated fatty acids. O Phosphoglycerides are to be considered amphiphilic. ONaturally, unsaturated fatty acids typically exist in the trans configuration.
Qualitative Tests for Lipids Explain why lipids are insoluble in polar solvents. How do oils and fats differ? How does the degree of unsaturation and structure of fats affect its functionality, for example in the case of trans fats? An unknown sample was tested if there is a presence of lipid, after the test it shows that it is positive for translucent test, soluble with chloroform, didn’t produce a pungent odor in acrolein test, didn’t produce red color for Baudouin Test, and violet color disappears in Huble’s Test. WHAT CAN YOU CONCLUDE FROM THESE RESULTS?
