a. How many distinct diglycerides can you prepare from glycerol and one each of the following fatty acids: lauric acid (C12H24O2) and arachidonic acid (C20H32O2)?
b. How many phosphatidylcholine isomers can you prepare from phosphatidylcholine ("lecithin") and one each of the following fatty acids: lauric acid (C12H24O2) and arachidonic acid (C20H32O2)?
c. In the biosynthesis of phospholipds there is a preference to put unsaturated fatty acids in the C-2 position of glycerol. Draw the skeletal structure of the phospholipid most likely to be formed from phosphatidylcholine (the structure of which is given), lauric acid (C12H24O2) and arachidonic acid (C20H32O2).
