    Study Notes

    Aromatic Amino Acid Derivatives

    • Modifications of aromatic amino acids, benzoic acids, and cinnamic acids lead to the formation of lignans, lignin, phenylpropenes, and coumarin.

    Combinations of Shikimate and Acetate Pathways

    • The combination of the shikimate pathway and the acetate pathway leads to the formation of styrylpyrones, flavonoids, stilbenes, flavonolignans, and isoflavonoids.

    Terpenoid Quinones

    • Terpenoid quinones are formed by combining the shikimate pathway with the terpenoid pathway.
