The effects of inclusion of different fatty acids in the medium on the rate of esterification of palmitic acid and its stereospecific distribution among the three positions of the triacyl-sn-glycerols by preparations of rat adipocytes in vitro have been determined. Myristic acid, stearic acid, oleic acid and linoleic acid were used as diluents and the concentration of the combined unesterified ...

The mechanism(s) by which fatty acids are sequestered and transported in muscle have not been fully elucidated. A potential key player in this process is the protein myoglobin (Mb). Indeed, there is a catalogue of empirical evidence supporting direct interaction of globins with fatty acid metabolites; however, the binding pocket and regulation of the interaction remains to be established. In th...

A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...

Palmitic acid was the main long chain fatty acids (LCFA) that accumulated onto the anaerobic sludge when oleic acid was fed to an EGSB reactor. The conversion between oleic and palmitic acid was linked to the biological activity. When palmitic acid was fed to an EGSB reactor it represented also the main LCFA that accumulated onto the sludge. The way of palmitic acid accumulation was different i...

The lymphoma plasma membrane glycoprotein, GP85, is a transmembrane glycoprotein that binds directly to ankyrin, a molecule known to link the plasma membrane with the underlying cytoskeleton. In this study, we have demonstrated that palmitic acid is incorporated into GP85 in vivo and that the amount of palmitic acid incorporated is greatly stimulated during lymphoma cap formation. The majority ...

The cholesterol-raising effect of dietary saturated fatty acids is largely accounted for by lauric, myristic, and palmitic acids. Dairy fat is a major source of myristic acid, and palm oil is especially rich in palmitic acid. Myristic acid is suspected of being much more cholesterolemic than palmitic acid, but direct comparisons have been lacking. We therefore fed 36 women and 23 men three diet...

To investigate the effect of acylated ghrelin on the activation of TLR4/NF-κB signaling pathway induced by palmitic acid in human monocyte-derived (THP-1) macrophages, THP-1 macrophages were cultured for 12 h by palmitic acid with various concentrations. The THP-1 macrophages was pretreated by acylated ghrelin at different doses for 4 h before cultivated by palmitic acid (200 μmol/L) for 12 h. ...

An earlier study from this laboratory dealt with the rates of U402 expiration when palmitic acid labeled with Cl4 was injected intravenously into rats (1). It was shown that, regardless of which carbon atom of this fatty acid was labeled (the carboxyl, the 6th, or the 11th) the amounts of Cl402 expired and the rates of its elimination were quite similar. It was therefore postulated that, once t...

Separation of rat sciatic nerve myelin proteins by sodium dodecyl sulfate-slab gel electrophoresis 18 h after injection of [3H]palmitic acid into the nerve demonstrated acylation of the PO protein. When sciatic nerve myelin labeled with [3H]palmitic acid was extracted with acidified chloroform/methanol or chloroform/methanol, the radioactivity associated with PO was retained. These results prov...
