Following the theme of this special issue, two new compounds, the P-flowers C(16)(PH)(8) and C(16)(PF)(8), are designed by us and subsequently characterized by quantum chemical computations. Their geometries and infrared signatures are analyzed and compared to those of the well-known sulflower C(16)S(8). Their electronic structure and aromaticity are examined using the electron localization fun...

Carotenoids and their fatty acid esters in the carapace of the spiny lobster Panulirus japonicus were investigated. Fatty acid esters of astaxanthin, adonixanthin, and pectenolone were characterized by (1)H-NMR and FAB-MS. The acylated position of adonixanthin and pectenolone monoesters was determined to be a hydroxy group at C-3' by (1)H-NMR. The fatty acids esterified with these carotenoids w...

A novel uronic acid-containing glycosphingolipid (UGL-1) was isolated from the ascidian Halocynthia roretzi. UGL-1 was prepared from chloroform-methanol extracts and purified by the use of successive column chromatography on DEAE-Sephadex, Florisil, and Iatrobeads. Chemical structural analysis was performed using methylation analysis, gas chromatography, gas chromatography-mass spectrometry, ma...

The cellular fatty acid composition of Halomonas salina, a moderately halophilic bacterium grown at different salt concentrations, is reported. Fatty acids C16:0 and C18:1 were major components and significant amounts of C16:1, C18:0 and cyc-C19:0 were also detected. The results showed clear chemotaxonomic relationships with recognized members of the genus Halomonas. The salt concentration grea...

Abstract A combination of lipidomics, transcriptomics and bioimaging has been used to study triacylglycerol synthesis deposition in the developing starchy endosperm wheat. The content TAG increased between 14 34 days after anthesis, from 50 115 mg/100 g dry wt about 35 175 mg/100 g two experiments. major fatty acids were C16 (palmitic C16:0 palmitoleic C16:1) C18 (stearic C18:0, oleic C18:1, li...

To improve beef quality, a selection of specific breeds for crossbreeding, genotyping, and candidate genes in breeding animals can be some the solutions. The objective this study was to determine effects FASN, SCD, GH on carcass fatness fatty acid (FA) composition intramuscular lipids crossbred Holstein × (Simmental, Belgian Blue, Limousin, Piemontese). allelic genotypic distribution polymorphi...

Developing highly selective and efficient bifunctional catalysts is an important issue for the hydroisomerization of long-chain n-alkanes. It vital to tailor balance isomerization cracking reactions in hydroisomerization. Herein, a Pt/hierarchical SSZ-32 catalyst was fabricated with sequential desilication–dealumination treatment boost n-hexadecane (C16). The pore structure acid sites zeolite w...
