Abstract The corrosion performance of phase change materials on stainless steel was studied using single fatty acid, acid/paraffin mixed and acid/paraffin/graphite composite as media. results show that the paraffin graphite to is very small; among them, stearic acid series are least corrosive can be used ideal energy storage medium for heat exchange devices.

Abstract The study examined the effect of stearin and paraffin adulteration wax foundation on brood survival. In combs formed a stearin-adulterated (10, 30, 50% stearin, which means: 3.9, 11.7, 19.5% stearic acid, respectively), survival decreased statistically significantly ( p ? 0.001) compared to rates noted pure beeswax foundation. appearance resembled so-called scattered although queens ov...

BACKGROUND Experimental evidence suggests that hepatic de novo lipogenesis (DNL) affects insulin homeostasis via synthesis of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs). Few prospective studies have used fatty acid biomarkers to assess associations with type 2 diabetes. OBJECTIVES We investigated associations of major circulating SFAs [palmitic acid (16:0) and steari...

Tetrahymena species contain relatively prominent glycosylphosphatidylinositol (GPI)-anchored proteins as well as their putative precursor phosphatidylinositol (PI) glycans. We have characterized the lipid components of the two principal T. mimbres PI glycans. Following their purification by preparative TLC, the PI glycans were hydrolysed in methanolic HCl or NaOH, and resulting lipids were anal...

The changes in lipid and fatty acid contents after soaking, cooking, germination and fermentation of three white sorghum varieties were studied to improve cereal quality. The results revealed that oil in raw sorghum varieties ranged from 3.58 to 3.91%, respectively and ‘Dorado’ represents the highest variety in oil content. As general trend after germination, oil content was decreased. Fatty ac...

We have investigated the influence of transmembrane pH gradients across large unilamellar vesicle membranes on the transbilayer distributions of simple lipids with weak base and weak acid characteristics. Trinitrobenzenesulfonic acid labeling results consistent with a rapid and complete migration of stearylamine and sphingosine to the inner monolayer of the large unilamellar vesicles are observ...

A novel cationic microbubble (MB) for improvement of the DNA loading capacity and the ultrasound-mediated gene delivery efficiency has been developed; it has been prepared with commercial lipids and a stearic acid modified polyethylenimine 600 (Stearic-PEI600) polymer synthesized via acylation reaction of branched PEI600 and stearic acid mediated by N, N'-carbonyldiimidazole (CDI). The MBs' con...

conclusions saturated fatty acids (sfas) served as a potential ligand for tlr4 and activated tlr4 signaling pathway, which might be involved in the pathogenesis. thus, sfas can accelerate the mechanism of inhibiting hbv replication in chb with nafld. objectives this study aimed to investigate whether the tlr4-mediated innate immunity stimulates the pathogenesis of chb in patients with nafld and...

Twelve pumpkin cultivars (Cucurbita maxima D.), cultivated in Iowa, were studied for their seed oil content, fatty acid composition, and tocopherol content. Oil content ranged from 10.9 to 30.9%. Total unsaturated fatty acid content ranged from 73.1 to 80.5%. The predominant fatty acids present were linoleic, oleic, palmitic, and stearic. Significant differences were observed among the cultivar...

In this work, we study and report the phase behavior of mixture lauric acid (LA) stearic (SA) inside polyvinyl alcohol (PVA)–polydimethylsiloxane (PDMS) nanofibrous mats woven using electrospinning technique.
