Glutathione stabilizes ascorbic acid in aqueous solution
This report shows that glutathione affects ascorbic acid degradation in aqueous solution resulting in a significant stabilization of the vitamin. For the GSH concentrations used in this work the effect was higher on diluted ascorbic acid solutions. It is also shown that for a fixed ascorbic acid concentration, as glutathione concentration increases the degradation reaction shifts from first to ...
متن کاملUptake of gas-phase nitrous acid by pH-controlled aqueous solution studied by a wetted wall flow tube.
Uptake kinetics of gas phase nitrous acid (HONO) by a pH-controlled aqueous solution was investigated by using a wetted wall flow tube. The gas phase concentration of HONO after exposure to the aqueous solution was measured selectively by the chemical ionization mass spectrometer in a high sensitive manner. The uptake rate of the gaseous HONO was found to depend on the pH of the solution. For t...
متن کاملQuantum mechanics investigation of acid dissociation constant of carboxylic acids in aqueous solution
According to the Bronsted definition, any compound which has a hydrogen atom is an acid, since itmay be lost as a proton. A thermodynamical cycle is proposed to calculate absolute pKa values forBronsted acids in aqueous solution. The equilibrium of dissociation of a Bronsted acid depends onthe interaction of the acid and its conjugate base with solvent molecules. There fore the pKa valuedepends...
متن کاملSonolysis of Carbon Dioxide, Nitrous Oxide and Methane in Aqueous Solution
Ultrasonic Waves, Carbon Dioxide, Nitrous Oxide, Methane, Free Radicals Water was irradiated with ultrasonic waves under an argon atmosphere which contained small amounts of carbon dioxide, nitrous oxide or methane. The yield of the products was measured as a function of the composition of the gas atmosphere. Maximum yields were observed at a few per cent of the added polyatomic gas. No chemica...
متن کاملReaction of the hydrogen atom with nitrous oxide in aqueous solution – pulse radiolysis and theoretical study
UB3LYP/cc-pVTZ computations using C-PCM, IEF-PCM, and SMD water-solvent models have been performed for the reaction of the Hc atom with nitrous oxide (N2O) producing N2 and cOH in aqueous solution. The Hc atom attacks the oxygen atom in the N2O molecule resulting in the formation of the [H–ONN] transition state and its decomposition into cOH and N2. This direct path requires 54.2 kJ mol 1 (PCM)...
