Skin Reaction Induced by Aldehydes for Food Flavoring Agents [PDF]

, 2001
Guinea pigs were sensitized intracutaneously for 7 days (0.1 ml of 1% aldehyde solution/day) with nine aldehydes (p-anisaldehyde, benzaldehyde, citral, ethylvanillin, furfural, n-octanal, l-perillaldehyde, piperonal and vanillin) which are used as the ...

Facile Palladium-Mediated Conversion of Ethanethiol Esters to Aldehydes and Ketones

Journal of the Brazilian Chemical Society, 1998
Treatment of ethanethiol esters with triethylsilane and palladium on carbon at ambient temperature furnished aldehydes. In addition, a variety of ketones have been prepared by a palladium-catalyzed reaction of ethanethiol esters with organozinc reagents.

Structural features of stomach aldehyde dehydrogenase distinguish dimeric aldehyde dehydrogenase as a ‘variable’ enzyme ‘Variable’ and ‘constant’ enzymes within the alcohol and aldehyde dehydrogenase families [PDF]

, 1991
Stomach aldehyde dehydrogenase was structurally evaluated by analysis of peptide fragments of the human enzyme and comparisons with corresponding parts from other characterized aldehyde dehydrogenases. The results establish a large part of the structure,

Stimuli‐Responsive Hierarchical Structuring Controls Survival and Programs Hydrogelation of Supramolecular Metallofibers

Advanced Materials, EarlyView.
Aqueous Zn(II) Salphen metallofibers decorated with PNIPAM undergo reversible, multi‐stimuli‐responsive hierarchical bundling. This higher‐order structuring kinetically stabilizes the otherwise fragile assemblies against dilution, acidic hydrolysis, and transmetallation, enables selective sorting of responsive fibers, and programs hydrogelation at ...

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.
