This review aims to give an update on the various facets of the general phenylpropanoid pathway, which is not only restricted to common lignin or flavonoid biosynthesis, but feeds into a variety of other aromatic metabolites like coumarins, phenolic volatiles, or hydrolyzable tannins.

2010年1月1日 · Phenylpropanoids contribute to all aspects of plant responses towards biotic and abiotic stimuli. They are not only indicators of plant stress responses upon variation of light or mineral treatment, but are also key mediators of the plants resistance towards pests (La …

2023年6月15日 · Phenylpropanoids are bioactive secondary metabolites biosynthesized by plants from the essential amino acid phenylalanine catalyzed by the enzyme PAL (phenylalanine ammonia-lyase), which is part of the shikimate pathway.

Phenylpropanoids are a group of plant secondary metabolites derived from phenylalanine and having a wide variety of functions both as structural and signaling molecules. Phenylalanine is first converted to cinnamic acid by deamination.

Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis.

Chalcones biosynthesis [ edit ] 4-Coumaroyl-CoA can be combined with malonyl-CoA to yield the true backbone of flavonoids, a group of compounds called chalconoids , which contain two phenyl rings.

Plant polyketide biosynthesis. A major class of molecules in the phenylpropanoid pathway is derived from a backbone wherein the phenylpropanoid unit that is derived from phenylalanine and activated through conjugation to CoA is extended by three acetyl moieties.

2008年5月9日 · Phenylpropanoid metabolism begins with the amino acid phenylalanine, which feeds into various biosynthetic pathways that generate a wide range of structurally related polyphenolic compounds. This review focuses on four sub-groups of these polyphenolic compounds – polyketides, stilbenes, isoflavones and catechins.
