The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. [1] .

Phenylpropanoids are named so because they have a six-carbon aromatic phenyl group and a three-carbon propene tail. These compounds are synthesized via the shikimate pathway from the amino acid phenylalanine to protect plants from harm, herbivores, and ultraviolet light.

May 9, 2019 · propanoid (plural propanoids) (organic chemistry) Any of a large group of compounds derived from the propenyl group of p-coumaric acid

Jan 1, 2010 · 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 …

Oct 20, 2023 · Phenylpropanoids are a wide class of natural compounds, which are synthesized by plants from phenylalanine or tyrosine, through a series of enzymatic reactions. Their name is derived from the six-carbon, aromatic phenyl group and …

In plants, all phenylpropanoids are derived from the amino acids phenylalanine and tyrosine. Phenylalanine ammonia-lyase (PAL, a.k.a. phenylalanine/tyrosine ammonia-lyase) is an enzyme that transforms L- phenylalanine and tyrosine into trans- cinnamic acid and p …

Sep 30, 2009 · 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 …

In recent years, some key players like phenylalanine ammonia lyases (PALs) from the phenylpropanoid pathway are proposed to have broad spectrum disease resistance (BSR) without yield penalties.

Aug 28, 2019 · In this review, we have presented the current knowledge on the biosynthesis, occurrence, biological activities of phenylpropanoids and their derivatives, along with the mechanism of action and their potential applications in various industries. Keywords: Phenylpropanoid; antimicrobial; antioxidant; caffeic acid; ferulic acid; hydroxycinnamic acid.

Phenylpropanoid biosynthetic pathway is activated under abiotic stress conditions (drought, heavy metal, salinity, high/low temperature, and ultraviolet radiations) resulting in accumulation of various phenolic compounds which, among other roles, have the potential to scavenge harmful reactive oxygen species.
