Witryna1 cze 2024 · Unexpectedly, this metabolic rescue is independent of increased ATP synthesis through glycolysis or oxidative phosphorylation, but dependent on ME1-produced NADPH and glutathione (GSH). Glutathione exists in reduced (GSH) and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. In healthy cells and tissue, more than 90% of the total glutathione pool is in the reduced form (GSH), with the remainder in the disulfide form (GSSG).

WitrynaGlutathione reductase is one of a chain of enzymes which serves to maintain glutathione in the reduced form. In vitro, this enzyme can function with either NADH or NADPH as hydrogen donor ( Francoeur and Denstedt, 1954; Kaplan and Beutler, 1968 ). In vivo, however, only NADPH is effective ( Beutler and Yeh, 1963; Rieber et al., 1968 ). Witryna12 kwi 2024 · The Titan protein. Titin — short for “Titan protein” — is the biggest known protein in humans. It’s built from around 27,000 amino acids .
