Curcuminoids as cell redox regulator Biology essay
Introduction. The main physiological role of RBCs or erythrocytes in red blood cells is to transport gases from the lungs to the tissues and maintain systemic acid-base balances. Furthermore, RBCs are well equipped with antioxidant systems, which essentially contribute to their function and functioning. integrity. Damage to the integrity of the red blood cells. Redox metabolism plays a central role in the cellular metabolism network, involves catabolic and anabolic reactions of diverse biomass and determines the redox state of cells. It can be measured quantitatively and easily in living cells and organisms with genetically encoded fluorescent sensors, providing new insights. In plants, photosynthesis generates redox intermediates with extremely negative redox potentials. Light-driven electron transport transfers electrons from the acceptor site of the photosystem IE m lt − to various acceptors, including oxygen E m. Blankenship, 2002. The redox intermediates include a: The complexity of redox regulation increases along the phylogenetic tree. • Complex regulatory networks enable a high degree of biological plasticity. modulates gene expression at all steps from transcription to protein synthesis. Fast responses are made possible by sensors with high reactivity. Low reactivity. This is of particular importance because apoptotic cell death is not observed in healthy cells. Numerous alleged biological antioxidants, both of plant and animal origin, such as urine. In living cells the most redox active metal ions are, and. Curcuminoids inhibit cell growth in human cancer cell lines at one dose. Redox signaling occurs when a biological system changes in response to a change in the level of a particular reactive oxygen species ROS or the shift in the redox state of a responsive group such as a dithiol-disulfide pair D Autreaux and Toledano, 2007 Finkel, 2011 Fourquet et al. 2008 Janssen-Heininger et al. 2008 Rhee, 2006;
