Epoxies modified by palmitic acid: From hot-melt adhesives to plasticized networks
(Wiley VCH Verlag, 2005-05)
Reactions taking place in a homogeneous solution of an epoxy monomer based on the diglycidyl ether of bisphenol A (DGEBA) and palmitic acid (PA), in the presence of benzyldimethylamine (BDMA), were investigated using ...
Biosynthesis of sphingolipids with very-long-chain pufa a hallmark of differentiating male germ cells
(Tech Science Press, 2019)
The sphingomyelins (SM) and ceramides (Cer) of rodent spermatogenic cells contain very-long-chain (C28-C32) polyenoic fatty acids (VLCPUFA), in non-hydroxy (n-V) and 2-hydroxy (h-V) forms. The SM and Cer species with n-V, ...

(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2016-03-28)
This work describes the synthesis of 1H-pyrazole-1-thiocarboxamide, thiazol-1H-pyrazol-5-ol, 1H-pyrazol-1-yl-tiazoles and 1-(3-alkyl-5-trifluoromethyl-5-hydroxy-4,5-dihydro-1H-pyrazol-1-yl)-alquen-1-ones were prepared from ...
A combined approach of electronic spectroscopy and quantum chemical calculations to assess model membrane oxidation pathways
(Royal Society of Chemistry, 2021-11)
Determining the UV absorbances at 234 nm and 280 nm enables a quick determination of the oxidation progress in lipid membranes. Nevertheless, experimental spectral results indicate a significant overlapping of bands arising ...
Non-traditional oily crops from arid and semiarid regions
(Research Signpost, 2010)
Vegetable oils are widely used in the food and nonfood industries. Many oil-bearing plants are native from the arid and semiarid regions of the world. While several crops originating from such regions have been expanded ...
