The effect of free fatty acids on endothelial cells
… (OxLDL) molecules e.g. oxidized polyunsaturated fatty acids (PUFAs), or saturated free fatty acids (FFA) are alone sufficient to decrease endothelial cells. This hypothesis was tested by incubating porcine aortic endothelial cells (PAECs) with various oxidized PUFAs and saturated FFAs. Twenty …

Biobehavioral responses to immune skew and free fatty acids
A well-described set of biobehaviors and cognitive dysfunction emerge after stimulation of the immune system with pathogen-associated or danger-associated molecular patterns, and the endogenous cytokines elaborated in the immunologic response are key effectors (Dantzer et al., 2008). Just as an …

Free Fatty Acids Associated with Induced Rancidity in Cream and Butter
… hydrolytic breakdown results in the release of free fatty acids, and it has been demonstrated that the lower molecular weight fatty acids which are freed are the major contributors to the rancid flavor (12, 54, 115). This lipase enzyme complex, which is normally inactive in fresh milk, can be …

The Roles of Free Fatty Acids and Inflammation in β-Cell Dysfunction
… adverse effects of chronically elevated plasma free fatty acids on β-cell function and mass and plays an important role in type 2 diabetes. The objective of my thesis was to investigate the role of inflammation in fat-induced β-cell dysfunction in vivo. I used in vivo models of 48h intravenous …

Production of Renewable Diesel Fuel via Hofer-Moest Decarboxylation of Free Fatty Acids
… performed on a graphite surface, electrolysis of free fatty acid (FFA) salts in an alcoholic electrolyte at potentials of at least 2.5 V/cell causes a two-electron Hofer-Moest decarboxylation. This reaction produces several hydrocarbons, ethers, and esters at a current efficiency of approximately …

Infarct size and free fatty acids in the early phase of acute myocardial infarction
… implications. Elevation of circulating free fatty acid (FFA) concentrations is a consistent feature (Kurien and Oliver, 1966; Oliver et al, 1968) of the profound, non-specific metabolic reaction associated with the onset of AMI (Opie, 1975). The FFA rise has been correlated with the …

Mechanisms into the development of fatty liver disease: role of free fatty acids and alcohol
Background: Alcohol and Free fatty acids such as palmitate are known to promote liver injury. However less mechanistic information is available regarding omega fatty acids ratios with/out alcohol. In healthy populations omega 6/3 ratios are between 1:1 to 4:1, whereas high ratios (>15:1) are …

Effects of Feeding Supplemental Eicosapentanoic Acid and Docosahexanoic Acid to Beef Females on Reproductive Responses and Free Fatty Acids
… of eicosapentanoic (EPA) and docosahexanoic acids (DHA) on reproduction in beef females. In experiment 1, cows (n = 31) were individually fed rumen protected fish meal (FM) or no fish meal (C) supplements. Estrus was synchronized and ovulation induced on d 37. Ovarian follicular growth and …

Effects of kinetin on distribution and exudation of free sterols and free fatty acids in Arachis hypogaea L. 'Argentine' under axenic conditions
… (10⁻⁶M and 10⁻⁴M) on distribution of free fatty acids and sterols in plant parts and root exudates of 57-day-old peanut plants grown in nutrient solutions under gnotobiotic conditions was studied. Kinetin was applied to the roots in the culture medium five days before harvest. Upon …

An in vitro study of the effects of free fatty acids on insulin mediated glucose uptake and metabolism by myocytes and fibroblast derived adipocytes
… the development of T2D. High levels of plasma free fatty acids (FFAs), particulary saturated FFAs such as palmitate, are associated with insulin resistance in muscle and adipose tissue. Monounsaturated FFAs, such as oleate and essential FFAs such as omega 3 and omega 6 are claimed to be …

Characterization and optimization of supercritical fluid chromatography with on-line Fourier transform infrared detection
… application of this technique to the analysis of free fatty acids is presented. Identification of carboxylic acids of carbon number 6-18 is made on several standard mixtures and on free fatty acids extracted from various complex samples. The spectral identification of the compounds as free fatty …

Engineering Saccharomyces ceresisiae for the Secretion of an Extracellular Lipase
… media. Saccharomyces cerevisiae can acquire free fatty acids from the growth media and a portion of these lipids can be converted into new lipid products. However, they cannot acquire complex lipids from the growth media unless a nonspecific lipase is included. To circumvent lipase addition, …

Fatty Acid-Mediated Inhibition of Host Cell Invasion by Cryptosporidium Parvum
… from bovine colostrum digests an unsaturated fatty acid that inhibits Cryptosporidium parvum sporozoite invasion of host cells in vitro. A panel of similar lipids with varying chain lengths and degrees of saturation were tested for evidence of inhibitory activity in order to determine the …

Studies on the fatty acid composition of human serum with special reference to the influence of hormones and other agents
A modified technique for separation of serum free fatty acids (FFA), t riglycerides, phospholipids and cholesterol esters by adsorption chromatography on a system of two columns, silicic acid and Florisil, has been elaborated for preparing samples for gas-liquid chromatographic analysis of serum …

Soybean Oil Deacidification Using Membrane Separation and Supercritical Carbon Dioxide
… of soybean oil triacylgycerols (TAGS) and added free fatty acids (FFA as oleic acid) was used. An evaluation of the solubility of soybean oil, oleic acid and linoleic acid in supercritical carbon dioxide provided the appropriate temperature and pressure conditions to use for the membrane …

Regulation of Fluid-phase Uptake in Podocytes by Albumin-associated Lipids
… lipid approach showed that certain unsaturated free fatty acids stimulate macropinocytosis through G protein coupled receptors, FFAR1, FFAR2 and FFAR3 and the Gβ/Gγ complex. Meanwhile, long-chain fatty acids were found to induce apoptosis in podocytes. These results suggest that podocytes sense …

An investigation of some factors affecting transdermal permeation.
… that T71 and T80 were related to melting of free fatty acids. The T80 endotherm displaying an irreversibility dependent on both temperature and time of exposure to elevated temperature. This is explained as being due to an interaction between free fatty acids and sterols within s.c. …

Effects of oil types and beta-carotene in repeated deep-fat frying of French fries
… Heated control oils showed much lower content of free fatty acids than fried oils with French fries. Palm stearin showed highest oxidative stability in p-Anisidine value and total polar compounds, however, the solidification of oils on the food surface during cooling make it unsuitable for …
