Phospholipids contain a glycerol backbone that is attached totwo fatty acid chains through an ester linkage and to a phosphateion through a phosphate ester linkage. An ester linkage is formedby the condensation reaction of the hydroxyl group (?OH) of theglycerol and the carboxylic acid functional group(O || ?C?OH)of a fatty acid. A phosphate ester linkage is formed from thehydroxyl group (?OH) and the phosphate ion. The phosphate ion isthen linked to a polar organic molecule through a phosphate esterlinkage. A phospholipid molecule containing two fatty acid chainsof 12 carbon atoms each having nocarbon-carbon double bonds in thechain and a polar organic group, X, is:

The phospholipid molecule is amphipathic, as it has a polar endand a nonpolar end.

Part A

A certain phospholipid molecule contains two fatty acid chainsof eight carbon atoms each having no carbon-carbon doublebonds in the chain. The phosphate ion is attached to a polarorganic molecule, X, just as highlighted in yellow in the figure inthe introduction.

Complete the structure of the phospholipid molecule using thestructure in the introduction. To include a X group in yourstructure, draw another atom, hover over the atom with the mouse,and then press the X key on your keyboard.

Drug designers often start with a “lead compound” that exhibits a mild therapeutic effect. The designers chemically modify the molecule in multiple ways and then test each variant to see whether it works better than the original lead compound. The modifications often include the addition or removal of functional groups. To mimic this process, start with the molecule shown below and perform the chemical modifications listed below (Steps 1 – 4).

 

 

         Step 1: Remove the entire carboxyl group and replace it with a hydrogen atom.

         Step 2: Replace two of the hydrogen atoms in the hexagonal ring structure with hydroxyl groups (note that only one hydroxyl group can be attached to a given carbon atom).

         Step 3: Locate the amino group that is not part of a ring structure and replace one of its hydrogen atoms with a CH3 group.

         Step 4: Add a CH3 group to one of the hydroxyl groups to form an ether linkage.

        

(a) Paste in a drawing of the final molecular structure. 

 

(b) What is the net (overall) charge of the original molecule at neutral pH? What is the net charge of the fully modified molecule (the one you drew) at neutral pH?
