Fatty Acid NanoCarriers (FAnC) are nanostructured fatty acid colloidal carriers that potentially be used as an alternative carrier system for cosmetic and pharmaceutical application. In this study, FAnCs were prepared from stearic acid as a combine mixture with oleic acid stabilized by Tween 60. The particle size and polydispersity of mixed FAnC were found to be increased with increasing oleic ...

1. Respiring slices of adult rat cerebrum have been shown to incorporate long-chain (14)C-labelled fatty acids into phospholipid. 2. Labelling was almost entirely confined to lecithin and ethanolamine phospholipid, only traces being present in serine phospholipid. 3. Palmitic acid, oleic acid and linoleic acid were incorporated more actively into lecithin than into ethanolamine phospholipid, bu...

BACKGROUND Obesity and overweight have been frequently observed in dogs and cats in recent years as in humans. The compositions of fatty acids (FAs) in the accumulated lipids in tissues of obese animals may have important roles in the process and mechanisms related to the onset of metabolic disorders. The purpose of this study was to evaluate the effects of a high fat (HF) diet, which contained...

The hydrogenation of all the methylene-interrupted cis,cis-octadecadienoic acids was examined using pure cultures of six rumen bacteria able to hydrogenate linoleic acid to stearic acid or its immediate precursor, trans-11-octadecenoic acid, after first conjugating the linoleic acid to cis,trans-9,11-octadecadienoic acid. Only the delta 14-cis,17-cis-isomer was not hydrogenated by at least one ...

Insoluble fatty surfaces are involved in many important interactions such as in biomembranes with soluble biological macro and micromolecules. In this paper we have studied the adsorption interaction of aqueous solution of DNA, some proteins and lactose on several sparingly soluble fatty substances namely milk fat, stearic acid, palmitic acid, phosphatidyl choline and cholesterol surfaces by me...

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...
