amino acids (aa) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. although, some table values are available on amino acids requirement, aa requirements may vary due to changes in dietary composition and breeding selection. thus amino acids requirements have remained an ongoing research topic. ...
introduction: cholesterol and fatty acids are two important components of the lipids. various fatty acids have different effects on plasma lipoproteins. consumption of saturated fatty acids tends to increase total plasma and ldl cholesterol levels. while polyunsaturated fatty acids reduce both ldl and hdl cholesterol, edible oil rich in monounsaturated fatty acid (mufa) however, tend to lower ...
Marine diatoms are important sources of fat and fatty acids that are considered for aquaculture and alternative energy sources, and under varying environmental conditions in algae. In order to influence the nitrogen deficiency and light intensity of the medium culture on the C.calcitrans fatty acid composition, algae was exposed to 4 nitrogen treatments (25,50,75 and 100% nitrogen) and light in...
Background: Amino acids have different effects on the growth of some dermatophytes. Some may encourage growth, while others inhibit it. The concentrations of some amino acids also are an important factor for their effect. To investigate the effects of amino acids on the growth of dermatophytes, the dermatophytes Trichophyton schoenleinii and Microsporum canis, obtained from Iran. Methods: In t...
In this study, three solid acid catalysts, namely mesoporous aluminophosphate-supported 12-tungstophosphoric heteropoly (HPW/MAP), aluminosilicate-supported (HPW/MAS), and gamma alumina-supported (HPW/?-Al2O3) were prepared characterized. Mesoporous aluminophosphate (MAP) aluminosilicate (MAS) synthesized via sol-gel hydrothermal methods, respectively, 25 wt.% of (HPW) was immobilized on the su...
