Multi-vanadium substituted polyoxometalates as efficient electrocatalysts for the oxidation of l-cysteine at low potential on glassy carbon electrodes [PDF]

open access: yes, 2006
The electrochemical behaviours of the sandwich-type complex [As2W18(VO)3O66]11- were studied in a pH 7 medium and compared with those of the three following Dawson-type vanadium-substituted complexes: [P2V2W16O62]8- (P2V2W16), [P2MoV2W15O62]8- (P2MoV2W15)

Biosynthesis of H2S is impaired in non-obese diabetic (NOD) mice [PDF]

open access: yes, 2008
Hydrogen sulphide (H2S) has been involved in cardiovascular homoeostasis but data about its role in animal models of diabetic pathology are still lacking.

Hormonal changes and redox imbalance in nicotine-induced testicular toxicity: the mitigating influence of D-ribose l-cysteine

open access: yesJournal of Basic and Applied Zoology, 2020
Background The effects of D-ribose l-cysteine on nicotine-induced testicular toxicity in male Wistar rats were examined in this study. Twenty healthy adult male Wistar rats with an average weight of 200 g were grouped as normal control, nicotine (2 mg/kg)

Effects of L-cysteine on the freeze-drying survival rate of Lactiplantibacillus plantarum LIP-1

open access: yesFood Science of Animal Products, 2023
Amino acids are often used as probiotic growth factors. Their addition to the growth medium is found to effectively enhance the resistance of the strain to adverse environments. In this research, we found that adding 0.05 g/L L-cysteine to culture medium

The association between exposure to volatile organic compounds and serum lipids in the US adult population

open access: yesLipids in Health and Disease, 2023
Background and Aim Epidemiological evidence on the relationship between exposure to volatile organic compounds (VOCs), both single and mixed, and serum lipid levels is limited, and their relationship remains unclear.

S-Nitroso-L-Cysteine Stereoselectively Blunts the Deleterious Effects of Fentanyl on Breathing While Augmenting Antinociception in Freely-Moving Rats

open access: yesFrontiers in Pharmacology, 2022
Endogenous and exogenously administered S-nitrosothiols modulate the activities of central and peripheral systems that control breathing. We have unpublished data showing that the deleterious effects of morphine on arterial blood-gas chemistry (i.e., pH,

Novel sulfur and selenium containing bis-α-amino acids from 4-hydroxyproline [PDF]

open access: yes, 2010
The synthesis of new substituted prolines carrying at C-4 a second α-amino acid residue is reported. The amino acid, l-cysteine or l-selenocysteine, is linked to the proline ring through the sulfur or the selenium atom, respectively.

Metabolic stress constrains microbial L-cysteine production in Escherichia coli by accelerating transposition through mobile genetic elements

open access: yesMicrobial Cell Factories, 2023
Background L-cysteine is an essential chemical building block in the pharmaceutical-, cosmetic-, food and agricultural sector. Conventionally, L-cysteine production relies on the conversion of keratinous biomass mediated by hydrochloric acid.

Mass Spectrometric Analysis of l-Cysteine Metabolism: Physiological Role and Fate of l-Cysteine in the Enteric Protozoan Parasite Entamoeba histolytica

open access: yesmBio, 2014
l-Cysteine is essential for virtually all living organisms, from bacteria to higher eukaryotes. Besides having a role in the synthesis of virtually all proteins and of taurine, cysteamine, glutathione, and other redox-regulating proteins, l-cysteine has ...

A mechanistic study of the EC′ mechanism – the split wave in cyclic voltammetry and square wave voltammetry [PDF]

open access: yes, 2016
In this paper, a detailed investigation of electrochemical reactions coupled with homogenous chemical steps using cyclic voltammetry (CV) and square wave voltammetry (SWV) was carried out to study the electrocatalytic (EC’) mechanism.
