Enzymes for the biosyntheses of the major phenylpropanoid derivatives in vascular
plants, namely flavonoids, lignins and cinnamyl esters are now known. The cinnamate
pathway to these compounds is reviewed briefly and brought up–to–date. Remaining problems,
such as the regulation by light and other factors as well as compartmentalization
of phenylpropanoid metabolism are being studied in many laboratories. The physiological
importance of low molecular weight cinnamyl compounds needs attention.

- Coniferyl Alcohol - Lignins - Chlorogenic Acid - Physiologically Active flavonoids
