Synthetic study of a moss-produced oxylipin and its structural revision
Tetrahedron, 2019 The proposed structure for a moss-produced acetylenic oxylipin (10-keto-type structure) was synthesized from a known glycidol derivative by an 11-step sequence involving epoxide ring opening with a terminal acetylene and enzymatic hydrolysis of a methyl ...

Oxylipins and oxylipin synthesis pathways in fungi
Applied Biochemistry and Microbiology, 2017Oxylipins are a family of oxygenated fatty acids that are very diverse with regard to origin, structure, and functions. These compounds are found in almost all living beings and serve both as autoregulators of the development of organisms and as communication molecules.

Regulation of oxylipin synthesis
Biochemical Society Transactions, 2000Two very common groups of oxylipins formed in plants involve the conversion of fatty acid hydroperoxides, such as hydroperoxy-octadecatrienoic acid, into further metabolites by allene oxide synthase and hydroperoxide lyase. Both of these oxylipin branch pathways appear to be ubiquitous or nearly so in plants, but the relative activities of these two ...

The Plant Journal, 2006
SummaryPractical guidelines for monitoring and measuring compounds such as jasmonates, ketols, ketodi(tri)enes and hydroxy‐fatty acids as well as detecting the presence of novel oxylipins are presented. Additionally, a protocol for the penetrant analysis of non‐enzymatic lipid oxidation is described. Each of the methods, which employ gas chromatography/

Bioprospecting for novel oxylipins in fungi: The presence of 3-hydroxy oxylipins in Pilobolus
Antonie van Leeuwenhoek, 2001As previously found in various members of the Mucorales, 3-hydroxy oxylipins in Mucor genevensis are associated with the sporangia, i.e. mainly the columella structure and between aggregating sporangiospores. To determine if this phenomenon is also true in distantly related members, the mucoralean fungus Pilobolus was examined.

Biosynthesis of oxylipins in non-mammals
Progress in Lipid Research, 2009Lipid 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.

Methods for the analysis of oxylipins in plants
Phytochemistry, 2009Plant 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.

Targeting esterified oxylipins by LC–MS - Effect of sample preparation on oxylipin pattern
Prostaglandins & Other Lipid Mediators, 2020A 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 ...

Abstract The oxidation of polyunsaturated fatty acids produces bioactive primary oxidation products known as oxylipins. In many biological matrices, the majority of oxylipins are bound (i.e. esterified), and a relatively small proportion (<10%) exists in the free form.
