Lubricants are indispensable pharmaceutical ingredients for preventing tableting failure due to powder adhesion the die wall. The impact of lubricants was evaluated with use Binding Identification Net Detriment (BIND) surface replication method. Raloxifene hydrochloride (RH) selected as a model chemical high adhesion, and four commercially available tablet – stearic acid, sodium stearyl fumarat...

The digestibility and absorption of dietary lipids depend on several factors including their fatty acid composition. In this study, apparent digestibility (AP) and the fatty acid profile of different dietary lipids, rich in saturated (SFA) and monoor polyunsaturated fatty acids (MUFA, PUFA), and also effects of some fatty acids especially stearic acid (18:0), was studied in rats. Twenty-four SD...

The incorporation of (14)C-labelled myristic, palmitic, stearic, oleic and linoleic acids in vitro into the lipids of bovine spermatozoa was measured at intervals from 2min to 2h. All acids were rapidly incorporated into diglycerides, myristic acid being metabolized to the greatest extent. Whereas the low incorporation of acids into total phospholipids reflected the relative stability of the ma...

background: the lipids of the spermatozoa membrane are important for the fluidity and flexibility of spermatozoa. however, spermatozoa’s lipids are the main substrates for peroxidation, which may provoke severe functional disorder of sperm. objective: the aim of this study was to investigate the fatty acids composition of spermatozoa in men with asthenozoospermia, asthenoteratozoospermia and ol...

Inverted-repeat-based gene constructs targeted against two key cotton seed-specific fatty acid desaturase genes, ghSAD-1, encoding stearoylacvl carrier protein delta9-desaturase and ghFAD2-1, encoding microsomal omega-6 desaturase, were transformed into cotton. The expression of ghSAD-1 and ghFAD2-1 in the inverted-repeat orientation resulted in increased levels of stearic and oleic acids, resp...

the effect of oleic and stearic acids on the water vapor permeability (wvp) and mechanical properties of sodium caseinate films was investigated. emulsifiers (span 80 and 85) were employed to produce the base mixture of film. tensile strength (ts), elongation (e) and young's modulus (ym) were obtained for both standard (without lipids) and hydrophobic films. results showed that the additio...

Decarboxylation of fatty acids over non-noble metal catalysts without added hydrogen was studied. Ni/C catalysts were prepared and exhibited excellent activity and maintenance for decarboxylation. Thereafter, the effects of nickel loading, catalyst loading, temperature, and carbon number on the decarboxylation of fatty acids were investigated. The results indicate that the products of cracking ...

A study was conducted to differentiate lard, chicken fat, beef fat and mutton fat using Gas Chromatography Mass Spectrometry (GC-MS) and Elemental Analyzer-Isotope Ratio Mass Spectrometry (EA-IRMS). The comparison of overall fatty acid data showed that lard and chicken fat share common characteristics by having palmitic, oleic and linoleic acid as major fatty acids while beef and mutton fats sh...

The purpose of this study was to investigate the fatty acid profiles in 18 soybean cultivars grown in Korea. A total of eleven fatty acids were identified in the sample set, which was comprised of myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1, ω7), stearic (C18:0), oleic (C18:1, ω9), linoleic (C18:2, ω6), linolenic (C18:3, ω3), arachidic (C20:0), gondoic (C20:1, ω9), behenic (C22:0), a...
