Water clustersDFTDissociation of ascorbic acid in water has been studied by using a cluster model. It was examined by density functional theory (DFT) with the В3LYP, M06, and wB97XD functionals and a 6–311++G(d,p) basis set. The thermodynamic and kinetic characteristics of proton ...
pH of water is 7. When a substance Y is dissolved in water, the pH bec... 02:08 The hydrolysis constang of 0.1M aqueous solution of sodium acetate if ... 00:52 The compound whose 0.1M solution is basic is 01:33 K(a) for ascorbic acid (HASc) is 5 xx 10^(-5). Calculate ...
The rats were randomly allocated into eight distinct groups for subsequent experimentation: (I) the control group was administered solely with distilled water as the vehicle (control); (II) NaAsO2-treated group (As); (III) NaAsO2 treated along with L-ascorbic acid and α-tocopherol ...
Ascorbic acid (AA) enhances the activity of TET2 likely by reducing catalytic site Fe(III) to Fe(II)21,22. Simultaneous 2-oxoglutarate decarboxylation provides two additional electrons needed for dioxygenase activity. AA may thus improve the function of intact TET2 in cases with heterozygousTET2MT,...
In this study, the correlation between SDS and ascorbic acid or its derivatives in aqueous solutions was assessed using spectroscopic and tensiometric methods. The influence of SDS interactions on the total antioxidant capacity of ascorbic acid/ascorbic acid derivatives was analyzed. The highest FRAP ...
Alumina sol was prepared from the catalytic hydrolysis of AIP under acid catalysis. Specifically, 2.04 g AIP and 0.5 g Hacac were firstly uniformly dispersed in 20.4 g ethanol. Then the mixture was added to 100 g hot water by stirring. Hydrolysis lasts for more than two hours...
The two metabolites that exhibited the most significant variations in all the cultivars studied with fold changes of up to 6.49 were ascorbic acid and prunasin. For the first time, these two metabolites have been proposed as potential biomarkers for endodormancy release in almond. Given the high...
The prepared ascorbic acid lithium is soluble in water and is organic lithium, can be applied to the field of medicines or foods, for example, can be used as antioxidant preservatives in foods, condiments or beverage, and can also be used as a good drug for treating mania, bipolar ...

Structurally, ascorbic acid belongs to the group of unsaturated polyhydroxy alcohols, presenting as a water-soluble ketolactone structured around a five-membered carbon ring (Fig. 2). Its notable reducing properties stem from double bonds at C2 and C3, coupled with hydroxyl groups at positions C2...
