Electrochemical behaviour of N-acetyl-l-cysteine on gold electrode—A tentative reaction mechanism [PDF]
, 2007 The electrochemical behaviour of N-acetyl-l-cysteine (NAC) has been investigated by linear and cyclic voltammetry on gold electrode at room temperature. The results showed two oxidation peaks under acid and neutral conditions and only one in basic medium.

Effects of Sulfur Amino Acids on Tyrosyl or Serine/Threonine Phosphorylation and Translocation of Cytosolic Compounds to Cell Membrane in Stimulus-treated Human Neutrophils [PDF]
, 2009 We investigated the effects of various sulfur amino acids on the phosphorylation of proteins and the translocation of cytosolic compounds to cell membrane in stimulus-treated human neutrophils using specific monoclonal antibodies.

Bioavailability of Organosulfur Compounds after the Ingestion of Black Garlic by Healthy Humans
Antioxidants, 2023 The consumption of black garlic has been related to a decreased risk of many human diseases due to the presence of phytochemicals such as organosulfur compounds (OSCs).

Long-time treatment by low-dose N-acetyl-L-cysteine enhances proinflammatory cytokine expressions in LPS-stimulated macrophages. [PDF]
PLoS ONE, 2014 N-acetyl-L-cysteine is known to act as a reactive oxygen species scavenger and used in clinical applications. Previous reports have shown that high-dose N-acetyl-L-cysteine treatment inhibits the expression of proinflammatory cytokines in activated ...

Functional characterization and structure-guided mutational analysis of the transsulfuration enzyme cystathionine γ-lyase from toxoplasma gondii [PDF]
, 2018 Sulfur-containing amino acids play essential roles in many organisms. The protozoan parasite Toxoplasma gondii includes the genes for cystathionine β-synthase and cystathionine γ-lyase (TgCGL), as well as for cysteine synthase, which are crucial enzymes ...

The endogenous production of hydrogen sulphide in intrauterine tissues [PDF]
, 2009 Background: Hydrogen sulphide is a gas signalling molecule which is produced endogenously from L-cysteine via the enzymes cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CSE).
