Innate Morphine is made in poppies.
A Reticuline epimer
converts to Thebaine, and then
enzymatic methyl
group oxidation
triggers a flow.
Codeinone →
Codeine
and,
lastly,
an enzyme
helps to effect
demethylation
of an aromatic
methoxy group to afford
the phenol-containing Morphine.
Natural synthesis in poppies.
