Arachidonic Acid Stress Impacts Pneumococcal Fatty Acid Homeostasis

Frontiers in Microbiology, 2018
Free fatty acids hold dual roles during infection, serving to modulate the host immune response while also functioning directly as antimicrobials. Of particular importance are the long chain polyunsaturated fatty acids, which are not commonly found in ...

Arachidonic acid in cellular activation [PDF]

Kidney International, 1999
The paper by Huang et al in this issue of Kidney International addresses the interesting and still unsettled question as to whether arachidonic acid (AA), in and of itself, is a specific pathophysiologic "mediator" of injury, independently of its further transformation into oxygenated derivatives1.

Inhibition of the Nicotinic Ion Channel by Arachidonic Acid and Other Unsaturated Fatty, Acids in Chromaffin Cells from Bovine Adrenal Medulla

CHIMIA, 1991
The effects of arachidonic and other cis-unsaturated fatty acids were investigated in cultured chromaffin cells from bovine adrenal medulla with respect to Ca2+ influx and secretion of catecholamines.

Designing New Natural‐Mimetic Phosphatidic Acid: a Versatile and Innovative Synthetic Strategy for Glycerophospholipid Research

Angewandte Chemie International Edition, Accepted Article.
Glycerophospholipids (GPLs) play important roles in cellular compartmentalization and signaling. Among them, phosphatidic acids (PA) exist as many distinct species depending on acyl chain composition, each one potentially displaying unique signaling function.

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

Mass Spectrometry Reviews, EarlyView., 2023
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.

Structured Lipids: Synthesis, Genetic Engineering, and Applications

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Lipids are essential to the human body, but some can be harmful. As a result, current research focuses on structured lipids (SLs), which are engineered to have specific fatty acid arrangements. These structural modifications can enhance both nutritional and physical properties.

Cytochrome P450 and arachidonic acid bioactivation: molecular and functional properties of the arachidonate monooxygenase

Journal of Lipid Research, 2000
The demonstration of in vivo arachidonic acid epoxidation and ω-hydroxylation established the cytochrome P450 epoxygenase and ω/ω–1 hydroxylase as formal metabolic pathways and as members of the arachidonate metabolic cascade. The characterization of the

Acute Hypercapnia/Ischemia Alters the Esterification of Arachidonic Acid and Docosahexaenoic Acid Epoxide Metabolites in Rat Brain Neutral Lipids. [PDF]

, 2020
In the brain, approximately 90% of oxylipins are esterified to lipids. However, the significance of this esterification process is not known. In the present study, we (1) validated an aminopropyl solid phase extraction (SPE) method for separating ...

Dietary N-3 polyunsaturated fatty acids decrease biliary cholesterol saturation in gallstone disease [PDF]

, 1992
Because fatty acid composition of biliary phospholipids influences cholesterol secretion into bile, we investigated whether replacement of n-1 monounsaturated or n-6 polyunsaturated fatty acids with n-3 polyunsaturated fatty acids in biliary ...

Comparison of Methods for the Preparation of Fatty Acid Methyl Esters for the Analysis of Omega‐3 Rich Oils by Gas Chromatography

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Fatty acid analysis is required in a wide range of industries, and conversion to fatty acid methyl esters followed by gas chromatography is by far the most common method of analysis. However, despite widespread use, there is no consensus on which derivatization method should be used or how the methods compare.
