Reference the following molecule: 1-stearoyl, 2-lenoleoyl(18:2Δ9,12) phosphatidylcholine.
Q: draw the platelet-activating factor. Explain the physiological relevance of each lipid in the molecule.
Please see the attached file for the Platelet activating factor using 1-stearoyl, 2-lenoleoyl(18:2Δ9,12) and phosphatidylcholine as reference molecule. Image shows, standard phosphoytidylcholine on one side and on the other side is platelet activating factor using 1-stearoyl (in Red box), 2-lenoleoyl(18:2Δ9,12)(in Green box) and phosphatidylcholine (the remaining part of molecule) as reference molecule.
C1 carbon is strearic acid (saturated fatty acid) which is connected by an ether linkage.
C2 carbon is linoleic acid (unsaturated fatty acid) whose short length because of double bond increases the solubility of PAF allowing it to function as a soluble signal messenger.
C3 is standard phosphatidylcholine
This structure allows platelet activating factor to inhabitat
and freely move in lipid bilayer. The fatty acid componen aslo
allows it to interact with lipoproteins.

Q.1: State and explain the concepts of factor abundance and factor intensity. (2 points) Factor abundance is a bilateral concept in factor proportions trade theory that has no definition when there are many countries and various factors of production. The present paper proposes a general definition, the Euclidean distance to the intersection of abundance rays with unit hyperplanes. Distance factor abundance is compared with other measures using a data set from the literature. Q. 2: Using the concepts above, state...
