Franich, Robert A. published the artcileConstituent acids of Pinus radiata stem cutin, Name: 17-Hydroxyheptadecanoic acid, the main research area is Pinus stem cutin carboxylic acid.

Stem cutin from P. radiata seedlings grown under winter and summer environmental conditions comprised n-alkanoic, (C10-C26), α,ω-alkanedioic (C14-C22), ω-hydroxyalkanoic (C12-C24), hydroxy-α,ω-alkanedioic, and polyhydroxyalkanoic acids. 9-Hydroxyheptadecane-1,17-dioic, 9-hydroxyoctadecene-1,18-dioic, 9-hydroxynonadecane-1,19-dioic, and 10,17-dihydroxyheptadecanoic acids are newly-identified constituents of gymnosperm cutin. Cutin grown under winter temperatures and photoperiod contained twice the amount of 9,16-dihydroxyhexadecanoic acid than that in summer-grown cutin, suggesting that the winter-grown cutin was formed from a highly crosslinked polymer, and that summer-grown cutin contained more linear polyester portions in the polymer.

Lin, Meei-Hua published the artcileComprehensive Mouse Skin Ceramide Analysis on a Solid-Phase and TLC Separation with High-Resolution Mass Spectrometry Platform, Formula: C17H34O3, the main research area is skin ceramide solid phase TLC mass spectrometry; Epidermal lipids; Mass spectrometry; Protein-bound lipids; Solid-phase extraction; Thin layer chromatography.

Lipidomic analyses by mass spectrometry (MS) of epidermal ceramides, a large family of lipids crucial to the permeability barrier of the skin, have been reported previously. To ensure the accuracy of lipid identification, we describe here the isolation of mouse newborn epidermal lipids followed by fractionation with solid-phase extraction columns, and lipidomic analyses by high-resolution MS for structural identification. We also describe here the employment of thin layer chromatog., an old but useful tool, in facilitating the structural characterization of the epidermal lipid species by MS.

Freire, C. S. R. published the artcileLipophilic extractives of the inner and outer barks of Eucalyptus globulus, Safety of 17-Hydroxyheptadecanoic acid, the main research area is Eucalyptus bark extract triterpenoid fatty acid ferulic acid ester.

The chem. compositions of the dichloromethane extracts of inner and outer barks of E. globulus were studied by gas chromatog.-mass spectrometry. The two fractions show very different chem. compositions: triterpenic acids, such as betulinic, ursolic and oleanolic acids, were the major components of the outer bark extract, whereas β-sitosterol and β-amirin along with palmitic, linoleic and oleic acids predominate in the inner bark extract Several α- and β-hydroxy fatty acids, recently reported for the first time as E. globulus wood components, were also identified in the outer and inner barks. In the outer bark extract, minor amounts of ferulic acid esters, also previously reported to occur in E. globulus wood were identified. In general, the inner bark lipophilic extractives resemble more closely that of E. globulus wood.

Rontani, J.-F. published the artcileOrigin and degradation of lipids in aeolian particles from a coastal area of the north-western Mediterranean Sea, Synthetic Route of 13099-34-8, the main research area is coastal area aeolian particle lipid degradation Mediterranean Sea.

The lipid content of eight samples of aeolian particles collected on the Frioul Islands (north-western Mediterranean Sea) during the year 2010 was investigated. Lipid analyses indicated a significant contribution of terrestrial higher plant debris to some of the samples, while meat cooking residues were also found. Specific degradation products of sterols and monounsaturated fatty acids were employed to assess the importance of biotic and abiotic degradation processes on land and during aeolian transport. Degradation of higher plant lipids on land appears to involve Type II (i.e., singlet oxygen-mediated) photooxidation during senescence and bacterial degradation processes in soils, while during aeolian transport this terrestrial material mainly undergoes autoxidation and/or Type I (i.e., radical-mediated) photooxidation and is relatively well preserved towards bacterial degradation In contrast, bacteria play a significant role in the degradation of meat cooking residues in these particles.

Panikashvili, David published the artcileThe Arabidopsis DESPERADO/AtWBC11 transporter is required for cutin and wax secretion, COA of Formula: C17H34O3, the main research area is Arabidopsis DSO transport protein cutin wax secretion.

The cuticle fulfills multiple roles in the plant life cycle, including protection from environmental stresses and the regulation of organ fusion. It is largely composed of cutin, which consists of C16-18 fatty acids. While cutin composition and biosynthesis have been studied, the export of cutin monomers out of the epidermis has remained elusive. Here, we show that DESPERADO (AtWBC11) (abbreviated DSO), encoding a plasma membrane-localized ATP-binding cassette transporter, is required for cutin transport to the extracellular matrix. The dso mutant exhibits an array of surface defects suggesting an abnormally functioning cuticle. This was accompanied by dramatic alterations in the levels of cutin monomers. Moreover, electron microscopy revealed unusual lipidic cytoplasmatic inclusions in epidermal cells, disappearance of the cuticle in postgenital fusion areas, and altered morphol. of trichomes and pavement cells. We also found that DSO is induced by salt, abscisic acid, and wounding stresses and its loss of function results in plants that are highly susceptible to salt and display reduced root branching. Thus, DSO is not only essential for developmental plasticity but also plays a vital role in stress responses.
