Aims: The objective of this study was to investigate the effect of free fatty acid length chain and unsaturated bond number on the heat resistance and recovery media of bacterial spores. Methods and results: For 6 species, bacterial spore heat resistances were estimated at different free fatty acid concentrations added to heating media or in recovery media. The addition of free fatty acids to h...

Kilka fish are known as the main industrial and pelagic species of Iran that are captured abundantly in the southern Caspian Sea. This study was conducted to survey the effectiveness of refinement steps on Kilka (Clupeonella delicatula) crude oil quality and fatty acid profiles. Neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...

Utilizing the human genome database, the recently developed G-protein-coupled receptor (GPCR) deorphanizing strategy successfully identified multiple receptors of free fatty acids (FFAs) and is proposed to play a critical role in a variety of physiologic homeostasis mechanisms. GPR40 and GPR120 are activated by medium- and long-chain FFAs, whereas GPR41 and GPR43 are activated by short-chain FF...

Free fatty acid concentrations in plasma measured after in vivo heparinisation are often overestimated because of ex vivo lipolysis of variable degrees. A new method has been developed using immediate extraction of blood which obviates this and shows that the true rise in plasma free fatty acid concentration after heparin in ambulant ward patients and in patients with acute myocardial infarctio...

Within adipose tissue, free fatty acids liberated by lipolysis may be re-esterified into newly synthesized triacylglycerol. We hypothesized that re-esterification may occur via an extracellular route, such that free fatty acids arising from lipolysis must leave the adipocyte and be taken up again before they can be re-esterified. We simultaneously measured rates of lipolysis, acylglycerol synth...

in this study, the effect of addition of three different levels of microbial lipase (0, 4, and 8.0 g lipase in 100 kg milk) was investigated on the physiochemical properties, free fatty acids, textural properties, and microstructure of lighvan cheese during ripening. the addition of lipase did not significantly affect ph, acidity, moisture, and salt content of lighvan cheese, but increased its ...

We have pioneered an in vitro pseudopod-generation model wherein suspended tumor cells are stimulated to form pseudopods into glass micropipettes in response to soluble collagen type IV (CIV). Pertussis toxin and removing intracellular calcium were found previously to be inhibitory to that process. We now extend those observations to dissect the roles of transmembrane calcium influx and circula...

Cultured bovine aortic endothelial cells that have been previously enriched with fatty acid are able to release free fatty acid (FFA) into the extracellular fluid. No stimulus other than the presence of albumin in the medium is needed to elicit the FFA release. Intracellular triglycerides appear to be the source of most of the FFA that is released. The released FFA is composed of a mixture of f...

Livers from normal fed male rats were perfused in vifro with equimolar quantities of either caproic, caprylic, lauric, pahnitic, stearic, oleic, linoleic, or linolenic acid. The concentration of free fatty acid in the medium was maintained at approximately 0.5 mu by constant infusion of the fatty acid during the experimental period of 4 hours. The rate of uptake of free fatty acid by the liver,...
