In vitro esterification of cholesterol by pancreatic juice and by acetone powder extracts of small intestine: the effect of unsaturated fatty acids upon esterification with saturated fatty acids

Journal of Lipid Research, 1965
The esterification of cholesterol by rat pancreatic juice and by extracts of acetone powders of rat small intestine was studied with palmitic, stearic, oleic, linoleic, and linolenic acids.

Homogeneously catalysed hydrogenation of unsaturated fatty acids to unsaturated fatty alcohols [PDF]

Journal of the American Oil Chemists' Society, 1965
AbstractThe use of copper and cadmium oxides or soaps as catalysts for the hydrogenation of unsaturated fatty acids to unsaturated fatty alcohols has been investigated. It is shown that copper soaps homogeneously activate hydrogen. When copper and cadmium oxides are used as catalysts, they react with the acid under formation of a homogeneous soap ...

Red Blood Cell Membrane Lipidomics: Potential Biomarkers Detecting Method for Plasma Volume Overload and Major Adverse Cardiovascular Events in Chronic Heart Failure Patients

Advanced Science, EarlyView.
A novel RBC indicator, ESI, is better than the traditional RBC indicators and is associated with CHF prevalence and in‐hospital death. RBC membrane lipidomics, Cer 18:0;O2/16:0, and LPE 18:0, are associated with plasma volume overload and MACE in CHF patients, but these plasma lipids could not.

Thiotemplated Polyketide Chain Fusion and Reductive Cyclization Build the Reactive Butenolide Core of Malleicyprol

Angewandte Chemie, EarlyView.
Malleicyprol, a virulence factor of notorious animal and human pathogens of the Burkholderia pseudomallei (BP) group, results from the fusion of two individual polyketide chains. The noncanonical condensation domain of the PKS–NRPS hybrid synthetase BurF forms an ester bond, and the terminal reductase domain mediates a reductive chain release followed ...

Unraveling Tissue‐Specific Fatty Acid Biosynthesis and Inter‐Tissue Crosstalk in Mice through Stable‐Isotope Tracing Metabolomics

Advanced Science, EarlyView.
Biosynthesis rates of 13 FFAs are quantitatively calculated in 15 tissues from glucose and an analytical framework to quantitatively calculate inter‐tissue communications of fatty acids between the liver and other tissues is developed. Moreover, the approach is extended to aging condition and a system‐wide decline of fatty acid synthesis in peripheral ...

PIP5K1A Suppresses Ferroptosis and Induces Sorafenib Resistance by Stabilizing NRF2 in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Inducing ferroptosis is a promising strategy for combating tumor resistance. Upregulated PIP5K1A competes with NRF2 for KEAP1 binding, which decreases the ubiquitination degradation of NRF2 and promotes its nuclear translocation, thereby suppressing ferroptosis, and ultimately driving hepatocellular carcinoma (HCC) tumorigeneses and sorafenib ...

High‐Specificity Spatiotemporal Cholesterol Detection by Quadrature Phase‐Shifted Polarization Stimulated Raman Imaging

Angewandte Chemie, EarlyView.
Utilizing quadrature phase modulation, the phase‐shifted polarization SRS (QP2‐SRS) microscope enables simultaneous measurement of the ρ‐related χ1111(3)$\chi _{1111}^{( 3 )}$ and χ1221(3)$\chi _{1221}^{( 3 )}$ components. In cholesterol molecular measurements, QP2‐SRS leverages the structural differences between cholesterol and other biomolecules to ...

Studies on the Unsaturated Lower Fatty Acids. On the Crystalline Derivatives of the Unsaturated Lower Fatty Acids [PDF]

Bulletin of the Chemical Society of Japan, 1937
Abstract (1) It is recognized that the tetradecenoic acid of “Tohaku” oil is tsuzuic acid. (2) The authors have prepared pure obtusilic, linderic, and tetra-decenoic acids from the “Tohaku” oil, and have determined their physical properties and the melting points of their crystalline derivatives.

A Tailored Artificial Biocatalyst for Bacterial Endophthalmitis Therapy via Enhanced Ferroptosis‐Like Death

Advanced Science, EarlyView.
A tailored bio‐targeted catalytic strategy based on a bacteria‐specific artificial biocatalyst (MoS2/Fe@mercaptophenylboronic acid@hyaluronic acid, MFBH) is proposed for treating bacterial endophthalmitis. This strategy exhibits high‐efficiency peptidoglycan‐targeted bactericidal efficacy in vivo following a single intravitreal injection of an ...

Multipoint Coordinative Capture of Olefinic Substrates Utilizing Metal‐Carbon Bonds by Macrocyclic Complex

Angewandte Chemie, EarlyView.
We have developed a macrocyclic tetranuclear palladium complex, which has four coordination sites within its inner cavity as a host molecule. The complex captured squalene (C30H50), a linear triterpene with six C═C double bonds, through multipoint palladium‐carbon bonds, and formed a unique host‐guest complex with a folded‐squalene structure.
