Glycerophospholipids (phosphoglycerides) are components of cell membranes. they are composed of a glycerol molecule with two fatty acids attached to the first and second carbon atoms, and a polar (hydrophilic) group attached through a phosphodiester linkage to the third carbon atom. each of the given molecules is a glycerophospholipid. fatty acid tails are represented by the symbols r1 and r2 . match each structure with the correct name. there will be one structure for each name.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
