The figures show glycerol, palmitinic acid and phytanyl, a C-20 hydrocarbon.

Exercise 1: By moving the proper molecules together, construct a glycerol-2-mono-ester-lipid like those that are components of bacterial membranes. (The proper bonds will automatically be established.)

Exercise 2: By moving the proper molecules together, construct a glycerol-2-mono-ether-lipid like the ones which are components of archaeal membranes. (The proper bonds will automatically be established.)
