The proximate composition, amino acid and fatty acid composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker (Pseudosciaena crocea) were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but lowest lipid content. Offshore cage-cultured fish showed significantly higher content of moisture and ...

Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...

Weanling male Wistar rats fed a choline-deficient diet develop acute kidney injury. Menhaden oil, which is a very important source of omega-3 fatty acids, has a notorious protective effect. The mechanism of this protection is unknown; one possibility could be that menhaden oil changes renal lipid profile, with an impact on the functions of biological membranes. The aim of this work was to study...

background: the modern dairy cows, due to intensive selection for higher milk production during past decades, have become more resistant to insulin. accompanied with dmi depression in per parturient dairy cow, insulin resistance may lead to a massive release of non-esterified fatty acids (nefa) to bloodstream which might act as a start point for development of other diseases. objectives: the pu...

Introduction: Considering importance of fatty acids in developing coronary artery disease (CAD) and lack of information about saphenous vein which is commonly used as coronary arterial bypass, in this study we investigated differences in fatty acids composition between saphenous vein and aorta tissues in patients with CAD. Methods: Biopsy samples of aortic tissues and saphenous veins as well as...

Continuous cultures of Chaetoceros muelleri, Skeletonema costatum and Rhinomonas reticulata of controlled biochemical compositions were fed to Mytilus edulis larvae over a 2-week period and the larval growth was assessed. The eggs as well as the larvae which subsequently developed were analyzed for their relative fatty acid profile and content; 27 fatty acids were identified by means of GCrMS. ...

Polyunsaturated fatty acids (PUFA) are important components of mammalian diets, and the beneficial effects of n-3 PUFA on human development and cardiovascular health have been well documented. Caenorhabditis elegans is one of the few animals known to be able to produce linoleic (LA, 18:2n-6) and alpha-linolenic (ALA, 18:3n-3) essential fatty acids. These essential PUFA are generated by the acti...

The fatty acid composition of eggs is highly reflective of the diet of the laying hen; therefore, nutritionally important fatty acids can be increased in eggs in order to benefit human health. To explore the factors affecting the hen's metabolism and deposition of fatty acids of interest, the current research was divided into two studies. In Study 1, the fatty acid profile of eggs from Bovan Wh...

The fatty acid (FA) profile of lipids extracted from the Varroa destructor parasitic mite and its host, drone-prepupae of Apis mellifera, was determined by gas chromatography (GC). The percentages of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) were generally similar in parasites and their hosts. Fatty acids were arranged in the follo...

The nonhydroxy fatty acid composition of Francisella tularensis is reported in detail. The double-bond configuration of the monounsaturated acids has been determined by capillary gas chromatography-mass spectrometry of the derivatized fatty acids. The monounsaturated fatty acids detected, in decreasing order of abundance, were 24:1 omega 15c, 18:1 omega 9c, 22:1 omega 13c, 20:1 omega 11c, 16:1 ...
