Production, Stability, and Antioxidative and Antimicrobial Activities of Two l-Ascorbate Analogues from Phycomyces blakesleeanus : d-Erythroascorbate and d-Erythroascorbate Glucoside.
d-Erythroascorbate (d-EAA), a five-carbon analogue of l-ascorbate (l-AA), and d-erythroascorbate monoglucoside (d-EAAG) are accumulated in Phycomyces blakesleeanus grown on glucose (99.5 and 1084 mug/...Read More
The influence of stereochemistry of antioxidants and flavonols on oxidation processes in a model wine system: ascorbic acid, erythorbic acid, +-catechin and (-)-epicatechin.
The stereochemical influence of antioxidant and flavanol compounds on oxidation processes in a model wine system was studied. The diastereoisomers, ascorbic acid and erythorbic acid, were used as anti...Read More
1,4-Dioxane-2,5-dione-type monomers derived from l-ascorbic and d-isoascorbic acids. Synthesis and polymerisation
l-Ascorbic and d-isoascorbic acids have been used as the starting materials for the preparation of (3R,4'S)-3-(2',2'-dimethyl-1',3'-dioxolan-4'-yl)-1,4-dioxane-2,5-dione ...Read More

Mechanisms and regulation of vitamin C uptake: studies of the hSVCT systems in human liver epithelial cells.
Humans use two sodium-ascorbate cotransporters (hSVCT1 and hSVCT2) for transporting the dietary essential micronutrient ascorbic acid, the reduced and active form of vitamin C. Although the human live...Read More
Since the double @Dgrx1@Dgrx2 mutant is hypersensitive to selenite we decided to evaluate mechanisms underlying this phenomenon and establish the roles of other components of yeast glutaredoxin system...Read More
Mammalian dimeric dihydrodiol dehydrogenase (DD) is identical to NADP+-dependent D-xylose dehydrogenase. A recent investigation showed that the three-dimensional structure of monkey DD is similar to t...Read More
Higher plants, protists and fungi possess cyanide-resistant respiratory pathway, which is mediated by alternative oxidase (AOX). The activity of AOX has been found to be dependent on several regulator...Read More
NAD+-specific D-arabinose dehydrogenase and its contribution to erythroascorbic acid production in Saccharomyces cerevisiae.
Erythroascorbic acid (eAsA) is a five-carbon analog of ascorbic acid, and it is synthesized from D-arabinose by D-arabinose dehydrogenase (ARA) and D-arabinono-gamma-lactone oxidase. We found an NAD+-...Read More
Mechanism of L-ascorbic acid uptake by rabbit corneal epithelial cells: evidence for the involvement of sodium-dependent vitamin C transporter 2.
To investigate the mechanism of L-ascorbic acid uptake by rabbit corneal epithelial cells and to functionally characterize the specific transporter involved in this translocation process....Read More
Preventing lipid oxidation during recovery of functional proteins from herring (Clupea harengus) fillets by an acid solubilization process.
It has previously been found that a process based on solubilization at pH 2.7 gives high yields of herring muscle proteins with good functionality. In this study, the development of lipid oxidation du...Read More
Cloning and characterization of gluconolactone oxidase of Penicillium cyaneo-fulvum ATCC 10431 and evaluation of its use for production of D-erythorbic acid in recombinant Pichia pastoris.
A D-erythorbic acid-forming soluble flavoprotein, gluconolactone oxidase (GLO), was purified from Penicillium cyaneo-fulvum strain ATCC 10431 and partially sequenced. Peptide sequences were used to is...Read More
Erythorbic acid, a stereoisomer of ascorbic acid with similar physicochemical properties, is widely used as an antioxidant in processed foods....Read More
The properties of novel bolaamphiphiles that carry epimers of vitamin C (L-ascorbic acid and/or D-isoascorbic acid) as hydrophilic head groups, and an interconnecting aliphatic C(12) chain (DD, DL, an...Read More
Determination of isoascorbic acid in fish tissue by hydrophilic interaction liquid chromatography-ultraviolet detection.
We're sorry this abstract is currently not available....Read More
We recently identified a microbial conversion of l-ascorbic acid (AsA) to l-erythroascorbic acid (eAsA), a five-carbon analog of AsA. In this paper, we show that ubiquitin plays a crucial role in this...Read More
Effect of headgroup chirality in nanoassemblies. Part 1. Self-assembly of D-isoascorbic acid derivatives in water.
L-(+)-Ascorbic acid and D-(-)-isoascorbic acid are epimers, with an opposite configuration at the C5 stereogenic chiral center. Single-chained surfactants that carry a L-ascorbic or d-isoascorbic acid...Read More
Determination of ascorbic acid and its related compounds in foods and beverages by hydrophilic interaction liquid chromatography
A new hydrophilic interaction liquid chromatography method for the simultaneous determination of ascorbic acid (AA), erythorbic acid (EA), 2-O-@a-d-glucopyranosyl-l-ascorbic acid (AA-2G) and 2-O-@b-d-...Read More

[structures: see text] A versatile (S)-3-(hydroxymethyl)butane-1,2,4-triol building block has been synthesized starting from D-isoascorbic acid, a common food preservative. The key transformation in t...Read More
Assessing plant response to ambient ozone: growth of ozone-sensitive loblolly pine seedlings treated with ethylenediurea or sodium erythorbate.
One-year-old seedlings from an ozone-sensitive half-sib family of loblolly pine (Pinus taeda L.) were transplanted into replicated plots in blocks in a large forest clearing near Nacogdoches, Texas. S...Read More
Considerable evidence exists that smoking significantly lowers the concentration of plasma antioxidants. While for most antioxidants this effect appears to result mainly from altered dietary habits, a...Read More
