Cclxv. Reactions of Pyruvic Acid with Thiolacetic Acid and Cysteine. by Ernst Friedmann and Joseph
BAUMANN [1885,2] observed that the action of ethyl-, phenyland p-bromophenylmercaptans on pyruvic acid led to the exothermic formation of substances which could be recrystallized from benzene and possesMed well-defined melting-points. Though stable in the solid state and in benzene solution, these compounds were rapidly broken down to their original constituents when dissolved in water, and wer...
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 اولDegradation of Lactic Acid and Pyruvic Acid in Belousov-Zhabotinskii Reactions
The temporal degradation of the Belousov-Zhabotinskii substrates lactic acid, pyruvic acid, bromoand dibromo pyruvic acid is investigated. The only final product of non-brominated substrates is acetic acid. From brominated educts only brominated acetic acids result. The con centrations of the stable products are determined as a function of time. The gross reactions are mainly based on simple c...
متن کاملPhotochemistry of aqueous pyruvic acid.
The study of organic chemistry in atmospheric aerosols and cloud formation is of interest in predictions of air quality and climate change. It is now known that aqueous phase chemistry is important in the formation of secondary organic aerosols. Here, the photoreactivity of pyruvic acid (PA; CH3COCOOH) is investigated in aqueous environments characteristic of atmospheric aerosols. PA is current...
متن کاملPhotoinduced oligomerization of aqueous pyruvic acid.
The 320 nm-band photodecarboxylation of aqueous pyruvic acid (PA), a representative of the alpha-oxocarboxylic acids widely found in the atmospheric aerosol, yields 2,3-dimethyltartaric (A) and 2-(3-oxobutan-2-yloxy)-2-hydroxypropanoic (B) acids, rather than 3-hydroxy-2-oxobutanone as previously reported. A and B are identified by liquid chromatography with UV and ESI-MS detection, complemented...
