Phenylpropanoids are a class of plant-derived organic compounds that are biosynthesized from the amino acid phenylalanine. They have a wide variety of functions, including defense against herbivores, microbial attack, or other sources of injury; as structural components of cell walls; as protection from ultraviolet light; as pigments; and as signaling molecules.

All phenylpropanoids are derived from p-coumaric acid and most from
cinnamic acid.
Thus, the formation of cinnamic acid from phenylalanine by the enzyme
phenylalanine ammonia-lyase is referred to as the branch-point between
primary metabolism (Shikimate) and secondary metabolism
(phenylpropanoids)
OVERVIEW
Pathways
o Flavonoids
o Anthocyanins
o Regulation
Several major classes of plant compounds are derived from phenylalanine:
including, flavonoids, coumarins, stilbenes, and benzoic acid.
