Controlled-potential oxidation of aliphatic amides
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1967Abstract A systematic study of the electrochemical oxidation of primary, secondary and tertiary aliphatic amides at platinum electrodes in aprotic solvents is reported. Results of product analyses, coulometry and cyclic voltammetry are presented. A mechanism is proposed which involves two different paths to stable products.

AMIDE METABOLISM IN YEAST: III. ALIPHATIC AMIDE METABOLISM IN CANDIDA UTILIS
Canadian Journal of Microbiology, 1961The partial purification and the properties of propionamide, valeramide, and hexanamide deamidases are described. The purified deamidases hydrolyzed propionamide, valeramide, and hexanamide to form ammonia and corresponding fatty acids. Maximum enzyme activity was obtained at 37 °C over a pH range of 6.7 to 7.8. The enzymes were inactivated at 55 °C in

A case study on the myth of emission from aliphatic amides
Methods and Applications in Fluorescence, 2016For several decades, aliphatic amidic compounds have been believed to be emissive. We report that this contention is incorrect and that the anomalous emission from amides originates in fluorescent impurities generated during their synthesis. In order to make this point, we have synthesized fluorescent compounds and have compared the absorption spectra ...

Process for detecting Helicobacter pylori using aliphatic amides
Analytical and Bioanalytical Chemistry, 2011Helicobacter pylori diagnosis is fundamental in the management of gastrointestinal pathologies, whose current clinical guidelines support a non-invasive 'test-and-treat' strategy. As such, the present work reports the basis of a new, low-cost, specific breath test based on the detection of volatile carboxylic acids resulting from the hydrolysis of ...

Determination of aliphatic amides by controlled-potential coulometry
Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1967Abstract The determination of a number of aliphatic amides in acetonitrile—LiClo 4 solution by controlled-potential oxidation at a platinum anode has been studied. The method gives an average precision of about 1% over a range of sample size from 0.2–2.0 mmoles.

Studies relating to the hydrolysis of aliphatic amides
1950The work described in this thesis is concerned with problems connected with the hydrolysis of the amide group but, although the whole investigation thus has a common theme, it falls conveniently into three divisions, dealing with γ amino butyramide, malonic acid amides and oxalic acid amides respectively. A study of the hydrolysis of γ amino butyramide
