Picolinic acid promoted oxidative decarboxylation of phenylsulfinylacetic acid by Cr(VI)

open access: yesBulletin of the Chemical Society of Ethiopia, 2016
The kinetics and mechanism of picolinic acid promoted reaction of phenylsulfinylacetic acid (PSAA) with Cr(VI) was carried out in aqueous acetonitrile medium under pseudo first order conditions. The reaction follows Michaelis-Menten type of kinetics with

Crystal structures of non-oxidative decarboxylases reveal a new mechanism of action with a catalytic dyad and structural twists

open access: yesScientific Reports, 2021
Hydroxybenzoic acids, like gallic acid and protocatechuic acid, are highly abundant natural compounds. In biotechnology, they serve as critical precursors for various molecules in heterologous production pathways, but a major bottleneck is these acids ...

Identification of the Products of Oxidation of Quercetin by Air Oxygenat Ambient Temperature

open access: yesMolecules, 2007
Oxidation of quercetin by air oxygen takes place in water and aqueous ethanol solutions under mild conditions, namely in moderately-basic media (pH ∼ 8-10) at ambient temperature and in the absence of any radical initiators, without enzymatic ...
