The Metabolism of 14C-Labeled cis and trans Isomers of Octadecenoic and Octadecadienoic Acids
The physical properties of common unsaturated fatty acids are altered when they are converted to their geometric isomers. For example, isomerization of the naturally occurring cis acid, oleic acid, to its trans form, elaidic acid, raises its melting point by 30”, changing it from a liquid to a solid at body temperature. Theoretically, such isomeric pairs might be expect.ed to differ in their me...

متن کاملRevised Methods for Purification of Ribosyl-trans-zeatin from Vinca rosea L. Crown Gall Tumor Tissue.
Ribosyl-trans-zeatin has been purified from Vinca rosea L. crown gall tumor tissue by using two new sequences of isolation procedures. Identification of the compound has been established by mass spectrometry, ultraviolet absorbancy spectra, chromatographic values, and growth activity. The isolation sequences eliminate the exposures to pH extremes and the strong cation-exchange resin used in the...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Comparative Activity of Isomers of Zeatin and Ribosyl-Zeatin on Funaria hygrometrica.
The activities of isomers of zeatin, ribosyl-zeatin, and 6-(gamma,gamma-dimethylallylamino) purine (i(6)Ade) on the moss Funaria hygrometrica are compared by measuring the ability of the cytokinins to induce callus or gametophores. The cis- and trans-ribosyl-zeatins were inactive, and therefore this kind of bioassay cannot be used as evidence for the presence or absence of a cytokinin in tests ...
