Using laser interference microscopy and Raman spectroscopy of frog myelinated nerve, it has been found that upon a train of action potentials passing along the fiber, the phase height (refractive index) of paranodal myelin declines while the ordering of fatty-acid tails therein increases. In ...
Fatty acid membrane Fatty acidsare single-chained amphiphilic molecules with a long, saturated or unsaturated hydrophobic aliphatic tail and a hydrophiliccarboxylic acidhead. The tails for the naturally occurring fatty acids contain about 4–28 carbon atoms. Similar tophospholipids, fatty acids can also...
POLYMYXIN DERIVATIVES HAVING SHORT FATTY ACID TAIL AND USES THEREOF PROBLEM TO BE SOLVED: To provide polymyxin derivatives and methods for treating a subject for gram negative bacterial infection by administering a combination of the polymyxin derivative and a second antibacterial agent. M Vaara,マルッ...
In the model chylomicron particles, it was possible to demonstrate at least two pools of oleic acid, one in the surface (the majority) and the other in the core, which are in fast exchange. Only the un-ionized FA is soluble in the triacylglycerol core, so that the partitioning favors ...
ARTICLE Received 24 Feb 2014 | Accepted 24 Jul 2014 | Published 9 Sep 2014 DOI: 10.1038/ncomms5805 Insights into mitochondrial fatty acid synthesis from the structure of heterotetrameric 3-ketoacyl-ACP reductase/3R-hydroxyacyl-CoA dehydrogenase Rajaram Venkatesan1, Shiv K. Sah-Teli1, Luqman...
Analyses of fatty acid biomarkers provided additional insights into the ecological pathways by which hippo-dung inputs can influence food web structure in aquatic ecosystems. It was expected that both SOM and POM from the Narrows would have greater terrestrial signatures relative to Charter’s Creek,...
Here, we test the hypothesis that elevating brain levels of the endogenous cannabinoid anandamide through either genetic deletion or pharmacological inhibition of its primary catabolic enzyme fatty-acid amide hydrolase (FAAH) will potentiate extinction in a fixed platform water maze task. FAAH (−/...
This complex consists of the fatty acid kinase, FakA, and an acyl carrier protein, FakB, and is known to impact virulence and disease outcomes. Despite some recent studies, there remain many outstanding questions as to the enzymatic mechanism and structure of FAK. To better address this ...
The main phenolic compounds found in Brazil nut are gallic acid, ellagic acid, vanillic acid, protocatechuic acid, and catechin (John and Shahidi, 2010). Sterols and tocopherols were found in a significant amount in these nuts. The chemical structure of some these bioactive compounds is given ...
