The monomers of lipids are called fatty acids. Draw the lipid monomer a fatty acid, labeling the hydrocarbon chain and the carboxyl end group. Be sure to show ALL of the atoms within the molecule (there are several different fatty acids in living things including oleic acid and stearic acid, each with a unique molecular formula).
Do not give handwriting solution.
A certain phospholipid molecule contains two fatty acid chains of eight carbon atoms each having no carbon-carbon double bonds in the chain. The phosphate ion is attached to a polar organic molecule, X, just as highlighted in yellow in the figure in the introduction.
Complete the structure of the phospholipid molecule using the structure in the introduction. To include a X group in your structure, draw another atom, hover over the atom with the mouse, and then press the X key on your keyboard.

Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default.
