Biosynthesis of Long-chain Fatty Acid Amides
The vast variety of long-chain fatty acid amides identified in biological systems is intriguing. The general structure of a fatty acid amide is R-CO-NH-X, where R is an alkyl group and X is derived from an immense variety of biogenic amines. Although structurally simple, the bioactivities of these …

Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
… for alternative herbicide sites of action. Very-long-chain fatty acid (VLCFA)-inhibiting herbicides are not labeled for use in U.S. rice production; however, this site of action (SOA) has been used with success in Asian rice. The VLCFA-inhibiting herbicides pethoxamid, pyroxasulfone, acetochlor, …

Dissecting phenotypic inheritance of very-long-chain fatty acid inhibitor resistance in waterhemp (Amaranthus tuberculatus) using a novel greenhouse assay: 'PRIM'
Weedy plant species, especially within the genus Amaranthus, capable of surviving the selective phytotoxic effects of an EPA-approved chemical at its most vulnerable growth stage, represent a clear and present danger to the United States and perhaps the world. Such a threat, if left unchecked, may …

Computational studies on polyunsaturated fatty acid uptake and its effects on antimicrobial resistance
… cholera, has the ability to uptake and utilize long chain polyunsaturated fatty acids up to 22 carbon atoms long. Before this discovery was made, conventional belief was that fatty acids of greater than 18 carbons long were toxic to bacteria. Further investigations have revealed that this uptake …

Pathological features of mitochondrial respiratory chain dysfunction
… include ATP generation by the respiratory chain, aspartate synthesis by matrix aminotransferases, and long-chain fatty acid catabolism by the beta oxidation pathway. Given the role of mitochondria in maintaining cellular physiology, mitochondrial dysfunction often leads to disease. One …

Human brain lipid fatty acid composition in relation to infant diet
… dying of sudden infant death syndrome. The fatty acid composition was analysed in these tissues by gas liquid chromatography after extraction and derivatisation. The subjects were divided according to their dietary history, either breast or formula feeding. Formula-fed infants were further …

The Metabolic Transitions Regulated by the Estrogen-related Receptor (ERR) in Drosophila melanogaster
… production of biomass (e.g., nucleotides, amino acids, and lipids) over efficiency of ATP generation. The conserved estrogen-related receptors (ERRs) are master regulators in controlling metabolic homeostasis, and good candidates for mediating the metabolic transition induced by hypoxia and …

Effect of Long Chain Fatty Acids on Anaerobic Digestion of Municiapal Sewage Sludge in Completely Mixed Reactors
… production. However, excessive addition of long chain fatty acid, the major content of FOG, has been reported to have inhibitory effects on the anaerobic digestion process and to cause operational challenges. In this study, high purity long chain fatty acids (LCFAs) including linoleic acid, …

Subsequent milk production and metabolic response of first-calf heifers fed whole raw soybeans during the last trimester of gestation
… treatment during gestation had no influence on long chain fatty acid concentrations in adipose tissue. Supplemental dietary fat provided by WSB for 90 d prior to parturition apparently altered the supply and metabolism of lipids in a manner that improved milk production during early lactation.

Gene discovery and expression profilng in the toxin-producing marine diatom, Pseudo-nitzschia multiseries (Hasle) Hasle
… Hasle, produces the the neurotoxin domoic acid, which is the cause of amnesic shellfish poisoning. The molecular characterization of this organism has been limited to date. Therefore, the focus of this thesis was to identify and initiate characterization of actively expressed genes that …

Composition of cuticular wax on the leaves of kalanchoe daigremontiana
… glutinol acetate and β-amyrin as well as very long chain fatty acid (VLCFA) derivatives including alkanes, primary alcohols, aldehydes, fatty acids, and alkyl esters. Cuticular wax composition in young K. daigremontiana leaves was dominated by triterpenoids, which made up over 70% of the lipid …

Novel genes required for proper cell envelope function in the plant symbiont Rhizobium leguminosarum
… for synthesis of the unique lipid A very long chain fatty acid (VLCFA). The third mutation mapped to a conserved hypothetical membrane protein, RL3501, that is part of a four gene operon. Both of these genes were critical for maintaining membrane stability in the presence of detergents, …

Physiological Bases and a Novel Genetic Determinant of Water-Use Efficiency (WUE)
… YK accumulates higher concentrations of free fatty acids and long-chain fatty acid derivatives than SH; whereas starch and sugars are more abundant in SH. The new and previously published SNPs were used to identify quantitative trait loci (QTL) correlated with WUE and/or biomass using a YK x …

Molecular regulation of the cardiac-enriched acetyl-CoA carboxylase isoform (ACCβ) : a novel target for therapeutic interventions in cardiovascular disease
… on a pivotal, rate-limiting step of cardiac fatty acid metabolism i.e. an upstream modulator of long-chain fatty acid importation into the mitochondrion. In the heart, long-chain fatty acids are transported into the mitochondrion by the rate-limiting enzyme, carnitine palmitoyl transferase 1 …

Characterization of Hydrophobically Modified Titanium Dioxide Polylactic Acid Nanocomposite Films for Food Packaging Applications
… and hydrophobic polymers such as polylactic acid (PLA) causes problems due to the tendency of TiO2 nanoparticles (TiO2) to agglomerate and form large clusters. A surface modification of TiO2 with long chain fatty acid may improve the compatibility between PLA and TiO2. The goal of this study …

The Association Between Hepatic Steatosis and Glucose Metabolic Dysfunction
Non-alcoholic fatty liver disease (NAFLD) is a growing global concern especially in Western countries, primarily resulting from poor nutritional habits. This disorder can manifest as early as the neonatal period suggesting that even in that period nutrition may play a role. While previous reports …

Increased Anaerobic Digestion Efficiency via the Use of Thermal Hydrolysis
… via their biogas production with and without long chain fatty acid addition and with or without thermal hydrolysis. This research was further carried out in two stages. First a mixture of unsaturated long chain fatty acids (hydrolyzed and unhydrolyzed) was used. The fatty acid mixture included …

Effect of Long-Chain Fatty Acids on Anaerobic Digestion
An investigation was carried out to study whether long-chain fatty acids (LCFAs) have an effect on digestion of waste sludge under anaerobic conditions. Four different kinds of LCFAs were used in this study. The 18 carbon series with 0, 1, 2 and 3 double bonds were studied to evaluate the degree of …
