Biosynthesis of oxylipins in non-mammals

Progress in Lipid Research, 2009
Lipid peroxidation is common to all biological systems, appearing in developmentally-regulated processes and as a response to environmental changes. Products derived from lipid peroxidation are collectively named oxylipins. Initial lipid peroxidation may either occur by enzymatic or chemical reactions.

Targeting esterified oxylipins by LC–MS - Effect of sample preparation on oxylipin pattern

Prostaglandins & Other Lipid Mediators, 2020
A major part of oxygenated metabolites of polyunsaturated fatty acids - i.e. eicosanoids and other oxylipins - in biological samples is found in the esterified form. Yet, their biological role is only poorly understood. For quantification of esterified oxylipins in biological samples current protocols mostly apply alkaline hydrolysis with or without ...

The regulatory functions of oxylipins in fungi: A review

Journal of Basic Microbiology, 2023
AbstractQuorum sensing (QS) is a communication mechanism between microorganisms originally found in bacteria. In recent years, an important QS mechanism has been discovered in the field of fungi, namely, the lipoxygenase compound oxylipin of arachidonic acid acts as a QS molecule in life cycle control, particularly in the sexual and asexual development

Methods for the analysis of oxylipins in plants

Phytochemistry, 2009
Plant oxylipins comprise a highly diverse and complex class of molecules that are derived from lipid oxidation. The initial oxidation of unsaturated fatty acids may either occur by enzymatic or chemical reactions. A large variety of oxylipin classes are generated by an array of alternative reactions further converting hydroperoxy fatty acids.

Oxylipin metabolism in response to stress

Current Opinion in Plant Biology, 2002
Oxylipins comprise a group of biologically active compounds whose structural diversity is generated by the coordinate action of lipases, lipoxygenases, and a group of cytochromes P450 that are specialized for the metabolism of hydroperoxy fatty acids. Research on oxylipins has focused mainly on the biosynthesis of the plant signaling molecule jasmonic ...

Oxylipins from Dracontium loretense

Journal of Natural Products, 2009
Four novel oxylipins (1-4) were isolated from the n-butanol extract of the corms of Dracontium loretense. Their structures were assigned by 1D and 2D NMR analyses and electrospray ionization multistage ion trap mass spectrometry (ESI-ITMS(n)) data. Relative configurations were assigned on the basis of combined analysis of homonuclear and heteronuclear (

Biosynthesis and analysis of plant oxylipins

Free Radical Research, 2015
The term oxylipin is applied to the generation of oxygenated products of polyunsaturated fatty acids that can arise either through non-enzymatic or enzymatic processes generating a complex array of products, including alcohols, aldehydes, ketones, acids and hydrocarbon gases.

Oxylipins and plant abiotic stress resistance

Biochemistry (Moscow), 2014
Oxylipins are signaling molecules formed enzymatically or spontaneously from unsaturated fatty acids in all aerobic organisms. Oxylipins regulate growth, development, and responses to environmental stimuli of organisms. The oxylipin biosynthesis pathway in plants includes a few parallel branches named after first enzyme of the corresponding branch as ...

Oxylipin covered ascospores of Eremothecium coryli

Antonie van Leeuwenhoek, 2005
Eremothecium coryli is known to produce intriguing spindle-shaped ascospores with long and thin whip-like appendages. Here, ultra structural studies using scanning electron microscopy, indicate that these appendages serve to coil around themselves and around ascospores causing spore aggregation.

Prostaglandins and oxylipins of corals

Russian Journal of Marine Biology, 2011
Literature data for the period from 1969 to 2010 on the distribution and chemical structures of prostaglandins, prostanoids, eicosanoids, and other cyclic and acyclic oxylipins from corals are summarized. The chemical structures of 97 compounds are given.
