protoporphyrinogen

protoporphyrinogen
pro·to·por·phy·rin·o·gen (pro″to-por″fə-rinґə-jən) a porphyrinogen (q.v.) in which two pyrrole rings each have one methyl and one propionate side chain and the other two pyrrole rings each have one methyl and one vinyl side chain. Fifteen isomers are possible but only one, type IX, occurs naturally, produced by oxidative decarboxylation of coproporphyrinogen; it is an intermediate in heme biosynthesis.
