Coumaroyl-coenzyme A is the thioester of coenzyme-A and coumaric acid. Coumaroyl-coenzyme A is a central intermediate in the biosynthesis of myriad natural products found in plants. These products include lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and other phenylpropanoids.{{cite journal|journal=Molecular Plant|year=2010|pages=2–20|doi=10.1093/mp/ssp106|title=Phenylpropanoid Biosynthesis|author=Vogt, T.|pmid=20035037|volume=3|doi-access=free}}
Biosynthesis and significance
It is generated in nature from phenylalanine, which is converted by PAL to trans-cinnamate. Trans-cinnamate is hydroxylated by trans-cinnamate 4-monooxygenase to give 4-hydroxycinnamate (i.e, coumarate). Coumarate is condensed with coenzyme-A in the presence of 4-coumarate-CoA ligase:
:ATP + 4-coumarate + CoA AMP + diphosphate + 4-coumaroyl-CoA.
