Thiols, an interesting family of compounds, are considered to be related to a wide range of biochemical events, including redox-, methyl transfer- and CoA-related reactions. 1 Intracellular thiols such as glutathione (GSH), cysteine (Cys), and homocysteine (Hcy) play a crucial role in maintaining biological redox homeostasis. 2 The levels of intracellular thiols change dramatically in response to oxidative stress, which has been associated with a number of diseases, including ...
