Formation of the E ring of chlorophyll is proposed to proceed via hydroxylation, oxidation and cyclisation of the C13 methylpropionyl side chain of MgPME. The chemical change at each step is highlighted. International Union of Pure and Applied Chemistry numbering of the relevant macrocycle carbons is indicated.
