The industrial wastes fly ash (FA) and polypropylene (PP) were used to develop novel green composites using a renewable, cheap coupling agent i.e. stearic acid. The fly ash (FA) particles were coated with stearic acid (SA) in different weight % like 0, 1, 2, 3 and 5. The SA coated fly ash particles were incorporated as filler in recycled polypropylene (RPP) matrix which was obtained from post-c...

Desaturation of [1-r4C]stearic acid, [lJ4C]palmitic acid, and [l-14C]stearoyl-CoA was measured in homogenates of lo-day-old rat brain. Desaturation was maximal with stearoyl-CoA at pH 6.0 to 6.6. With free fatty acids, monoene formation was maximal at pH 7.2 to 7.6; stearic acid was more actively desaturated than palmitic acid. Activity with stearic acid or stearoyl-CoA was linear with protein ...

The objective of this study was to compare the effects of linoleic acid (cis,cis-C18:2(n-6)) and its hydrogenation products elaidic (trans-C18:1(n-9)) and stearic acid (C18:0) on serum lipoprotein levels in humans. Twenty-six men and 30 women, all normolipemic and apparently healthy, completed the trial. Three experimental diets were supplied to every subject for 3 weeks each, in random order (...

The biomechanics stress and chronic inflammation in obesity are causally linked to osteoarthritis. However, the metabolic factors mediating obesity-related osteoarthritis are still obscure. Here we scanned and identified at least two elevated metabolites (stearic acid and lactate) from the plasma of diet-induced obese mice. We found that stearic acid potentiated LDH-a-dependent production of la...

The fatty acid composition was evaluated in field grown sesame cultivars (Sesamum indicum L.) at New Developmental Farm Agriculture University, Peshawar, KPK Pakistan during summer 2012. The experiment was laid out in RCBD with split plot arrangement having four replications each. Two sesame cultivars viz., local black and local white were sown at different dates i.e. 20 June, 10 and 30 July, a...

In this study, a gas chromatographic method is presented for the determination of calcium stearate after its conversion to stearic acid in a polymeric matrix. A solution of hydrochloric acid in 2-propanol is used as an extracting solvent of calcium stearate and its converter to stearic acid. For stearic acid preconcentration before its injection to a separation system, a recently presented extr...

Soybean oil has a wide variety of uses, and stearic acid, which is a relatively minor component of soybean oil is increasingly desired for both industrial and food applications. New soybean mutants containing high levels of the saturated fatty acid stearate in seeds were recently identified from a chemically mutagenized population. Six mutants ranged in stearate content from 6-14% stearic acid,...

Superhydrophobic surfaces were prepared using a two-step method that involved the etching of AZ31 and AZ91 magnesium alloys then modifying etched with stearic acid. Magnesium ZnCl2 SnCl2 exhibited roughened micro- nanoscale hierarchical structures consisting two chemically distinct regions (Zn/Zn(OH)2 or Sn/SnO2 Mg(OH)2). An optimum time ten minutes was chosen for both etchants. highest contact...

Suggestions have been made that saturated fatty acids with 12-18 carbon atoms, stearic acid (18:0) in particular, are prothrombogenic. These suggestions are based mainly on in vitro measurements. In the present study the effect of dietary fats high in stearic or myristic acid (14:0) on plasma triacylglycerol concentrations and key variables of blood aggregation (in vitro and in vivo), coagulati...
