Phenolic compounds in Vitis vinifera contribute important flavor, functionality, and health qualities to both table and wine grapes. The plant phenolic metabolic pathway has been well characterized, however many important questions remain regarding the influence of environmental conditions on pathway regulation. In this book we aim at giving a general overview on metabolic engineering of plant secondary metabolism, and show by a series of reviews the progress made in applying molecular biology to alter the production of certain compounds.

  Lignin engineering is an attractive strategy to improve lignocellulosic biomass quality for processing to biofuels and other bio-based products. However, lignin engineering also results in profound metabolic consequences in the plant. We used a systems biology approach to study the plant’s response to lignin perturbations.

Phenolic compounds are the most widely distributed secondary metabo lites, ubiquitously present in the plant kingdom, even if the type of compound. Phenolic compounds regulate the various metabolic functions including structure and growth, pigmentation and are resistant to different pathogens in plants (Naumovski ).

Regulation of Secondary Product and Plant Hormone Metabolism contains the proceedings of the 12th Meeting of the Federation of European Biochemical Societies held in Dresden, Germany in The meeting provided a forum for discussing progress in understanding the regulation of the metabolism of secondary products and plant hormones.

Phenylpropanoids occupy a central role in the biosynthesis of phenolic compounds, which are ubiquitous in the plant kingdom. The most frequent pathway for the formation of phenylpropanoids and other phenolics begins with the aromatic amino acids l.

Phenolic compounds are considered secondary metabolites within the physiology of a plant. They have different functions, such as pollination systems, sun protection, protection against pathogens and diseases, ch on these compounds has increased due to the number of molecules they can include and the different biological activities they demonstrate.

It is important to know Author: Marcos Soto-Hernández, Rosario García-Mateos, Mariana Palma-Tenango. Phenolic compounds are secondary metabolites found most abundantly in plants. These aromatic molecules have important roles, as pigments, antioxidants, signaling agents, the structural element lignan, and as a defense mechanism.

The expression of phenolic compounds is promoted by biotic and abiotic stresses (e.g., herbivores, pathogens, unfavorable temperature Cited by: 3.

Abstract “Plant phenolics” and “polyphenols” are secondary natural metabolites arising biogenetically from either the shikimate/phenylpropanoid pathway, which directly provides phenylpropanoids, or the “polyketide” acetate/malonate pathway, which can produce simple phenols, or both, thus producing monomeric and polymeric phenols and Phenolic compounds and metabolic regulation book, which.

In biochemistry, naturally occurring phenols refers to phenol functional group that is found in natural products. Phenolic compounds are produced by plants and microorganisms.

Organisms sometimes synthesize phenolic compounds in response to ecological pressures such as pathogen and insect attack, UV radiation and wounding. As they are present in food consumed in human.

This system may serve to study the regulation of the biosynthesis of (poly)phenolic compounds in globe artichoke and the genetic basis of this metabolic regulation. By means of HPLC-PDA and accurate mass LC-QTOF MS and MS/MS analyses, the major phenolic compounds in globe artichoke leaves were identified: four isomers of dicaffeoylquinic acid Cited by: The phenolic content in wine refers to the phenolic compounds—natural phenol and polyphenols—in wine, which include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine.

These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers and flavanol. Rice (Oryza sativa L.) is an important food crop providing energy and nutrients for more than half of the world population.

It produces vast amounts of secondary metabolites. At least secondary metabolites from rice have been identified in the past 50 years.

They mainly include phenolic acids, flavonoids, terpenoids, steroids, alkaloids, and their derivatives. These Cited by: 7. Phenolic compounds make up one of the major families of secondary metabolites in plants, and they represent a diverse group of compounds.

Phenolics can be broadly divided into non-soluble compounds such as condensed tannins, lignins, and cell-wall bound hydroxycinammic acids, and soluble phenolics such as phenolic acids, phenylpropanoids Cited by:   Influence of Phenolic Compounds on [14 C]-Tyramine Oxidation.

Figure 5 shows that pargyline inhibited the MAO-dependent [[sup]C]-tyramine oxidation by hAT. As expected, and accordingly with the above-used method, semicarbazide was virtually unable to abolish this activity.

Surprisingly, phenolic compounds did not inhibit MAO activity totally. The PAL Pathway To SA. Phenylalanine ammonia-lyase (EC ), the first enzyme in the phenylpropanoid pathway, converts phenylalanine (Phe) to trans-cinnamic acid (t-CA) and NH 3 via a non-oxidative deamination reaction (Raes et al, ; Rohde et al, ).

t-CA is a precursor for the biosynthesis of diverse phenolic compounds; in Arabidopsis, these Cited by: Phenolic compounds have gained wide interest in recent years and become one of the hotspots in the field of food research. Through a series of biological regulation techniques, various phenolic acids can be enriched in plant food materials, thereby effectively improving their nutritional : Chen ZhiJie, Wu JiaQi, Ma Yan, Wang Pei, Gu ZhenXin, Yang RunQiang.

Ligand preparation. The structures of berry phenolic compounds and citrus flavonoids studied are shown in Fig stilbenoid resveratrol and the citrus flavonoids luteolin, apigenin, flavone, naringenin, and hesperetin were selected due to their low DPP-IV IC 50 (μM) values compared to diprotin A, a known DPP-IV inhibitor [].Compounds in the flavonoid class of anthocyanins Cited by: 5.

In addition, downregulation of key genes of the lignin biosynthesis pathway in tomato (lignin shares common precursors with phenolic compounds) resulted in metabolic flux being redirected into the production of other phenolic compounds (e.g., chlorogenic acid, rutin).

Another approach involves genetic manipulation of regulatory genes like by: 1. The phenolic compounds of 25 peach, nectarine, and plum cultivars were studied and quantified by HPLC−DAD−ESIMS.

Hydroxycinnamates, procyanidins, flavonols, and anthocyanins were detected and quantified. White and yellow flesh nectarines and peaches, and yellow and red plums, were analyzed at two different maturity stages with consideration of both peel and flesh.
