Chemical compound

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.

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 {\displaystyle \rightleftharpoons } AMP + diphosphate + 4-coumaroyl-CoA.
