In lb is research, adsorption of some amino acids and their complenation with manganese (II) ion on carbonnanotube (MWCNT) by using of four relations Langmuir, Freundlich. Temkin and Harkins -Jura imitherms wasinvestigated. From this relations. Freudlich and Temkin relations predict good equilibrium diagram in, isothermcondition. we could compute the theoretical constants by excel software. Hy ...

dietary fatty acids play a critical role in modulation of airway inflammation in asthma. this study was conducted to compare dietary intakes of essential fatty acids and serum levels of inflammatory factors in asthmatic and healthy adults, and to examine the potential relationship between inflammatory markers and dietary fatty acids. in this case-control study, 47 asthmatic patients (26 males a...

the aim of this study was to investigate the effect of different concentration of royal jelly’s fatty acids (0.0, 125, 250, 500, 1000 µg/ml and 50 µl dmso) on in vitro maturation of goat oocyte. goat ovaries were collected from local slaughterhouse and transported to the laboratory and cocs were cultured into the maturation media supplemented with different concentration of royal jelly’s fatty ...

reactions of n-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular aza-wittig cyclization in ch2cl2 in excellent yields. the structures of the products were deduced from...

a highly efficient method for the oxidation of aldehydes to carboxylic acids using polyvinylpolypyrrolidone supported - boron trifluoride (pvpp-bf3) in the presence of 35% hydrogen peroxide has been developed in acetonitrile at 60 °c. this procedure cleanly oxidizes variety of aldehydes to the corresponding carboxylic acids. oxidative esterification of benzaldehyde utilizing pvpp-bf3/h2o2(35%) ...

the esterification of free fatty acids (ffa) with methanol is studied using sulfonated porous carbon (spc) as catalyst. in compare to the amorphous sugar catalyst and protonated nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. the highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol h+ and mole ratio of meoh...

objectives: the objective of this research was to investigate the chemical composition and antibacterial activities of the fatty acids and essential oil from various parts of ligularia persica boiss (l. persica) growing wild in north of iran. materials and methods: essential oils were extracted by using clevenger-type apparatus. antibacterial activity was tested on two gram-positive and two gra...

boraginaceae family is known as a medicinal plant classified in dicotyledons.  it is originated from asia (middle east). the aim of this study was to evaluate ingredient between 4 species of boraginaceae family based on physiological & phytochemical traits as well as seed fatty acid contents.  4 species (e. russicum, e. italicum, e. amoenum, and b. officinalis ) were evaluated carefully. all se...
