Understanding polysulfide evolution in wine: insights from accelerated ageing and real-time cellaring in different packaging [PDF]

Food Chemistry: X
Volatile sulfur compounds (VSCs) and non-volatile biothiols play a crucial role in wine quality. Certain sulfhydryl compounds can react to form odourless polysulfides (RSSnSR′) that potentially contribute to the development of sulfur off-odours during ...

Elemental Sulfur Inhibits Yeast Growth via Producing Toxic Sulfide and Causing Disulfide Stress

Antioxidants, 2022
Elemental sulfur is a common fungicide, but its inhibition mechanism is unclear. Here, we investigated the effects of elemental sulfur on the single-celled fungus Saccharomyces cerevisiae and showed that the inhibition was due to its function as a strong

Introduction of a More Glutaredoxin-like Active Site to PDI Results in Competition between Protein Substrate and Glutathione Binding

Antioxidants, 2022
Proteins in the thioredoxin superfamily share a similar fold, contain a -CXXC- active site, and catalyze oxidoreductase reactions by dithiol-disulfide exchange mechanisms. Protein disulfide isomerase (PDI) has two -CGHC- active sites.

Environmentally friendly recycling system for epoxy resin with dynamic covalent bonding

Science and Technology of Advanced Materials, 2021
Recycling of epoxy resin and its composites is extremely difficult due to its thermoset nature. In this study, we proposed the environmentally-friendly recycling system of epoxy resin with dynamic covalent bonding in the assistance of cysteine-containing

The mammalian peroxisomal membrane is permeable to both GSH and GSSG – Implications for intraperoxisomal redox homeostasis

Redox Biology, 2023
Despite the large amounts of H2O2 generated in mammalian peroxisomes, cysteine residues of intraperoxisomal proteins are maintained in a reduced state.

Glutathione cycle in diquat neurotoxicity: Assessed by intrastriatal pre-treatment with glutathione reductase [PDF]

Acta Veterinaria, 2013
Diquat (DQ) neurotoxicity mechanisms are unknown, although, it's systemic toxicity is mediated by free radical reactions. The role of glutathione cycle was assessed by glutathione reductase (GR) applied in the pre-treatment of DQ poisoning.

NOV-002, a mimetic of glutathione disulfide [PDF]

Expert Opinion on Investigational Drugs, 2008
Oxidative signaling to modulate redox-sensitive cell functions is a heretofore unexploited approach to developing new drugs for poorly treated oncology indications, where current therapies are often only palliative and accompanied by severe toxicities.Clinical and non-clinical findings with NOV-002 (a mimetic of glutathione disulfide that represents ...
