متن کاملAnalysis of Oleic Acid-rich Edible Oils by Mass Spectrometry Analysis of Oleic Acid-rich Edible Oils by Mass Spectrometry
Introduction. Edible oils containing > 60 % monoenoic acids (i. e. oleic acid), in particular olive oil and Canola oil have been shown to exhibit beneficial effects on lipid metabolism in human (LDL-cholesterol blood levels, triacylglycerol blood levels) within the last few years [1]. These findings are in contrast to earlier recommandations by nutrition experts who strongly favored high-linole...
متن کاملIdentification of volatile organic compounds of some Trichoderma species using static headspace gas chromatography-mass spectrometry
Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...
متن کاملstudy of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اول[Identification of amino acid phenylthiohydantoins by mass spectrometry].
The unequivocal identification of phenylthiohydantoins of the 20 amino acids usually occurring in proteins is possible by mass spectrometry and by combined gas chromatography-mass spectro metry. The method is sensitive enough to be applied to the identification of phenylthiohydantoins obtained from automated Edman degradations of polypeptides. Mass spectra of 21 amino acid phenylthiohydantoins...
