Thiols are molecules with the sulfhydryl group-SH attached to one of their carbon atoms. WebTherefore, the thiol metabolites may also be relevant in maintaining the homeostasis of PTP1B S-sulfhydration. In general, we demonstrated a feasible method for determining protein S-sulfhydration and revealed that PTP1B S-sulfhydration mediated by H 2 S and redox state was involved in the response and regulation in insulin signaling.
WebThiol compounds including predominantly glutathione (GSH) are key components of redox homeostasis, which are involved in the protection and regulation of mammalian cells. The assessment of cell redox status by means of in situ analysis of GSH in living cells is often preferable over established assays in cell lysates due to fluctuations of the GSH pool.
