This proved that respiring cells are entirely capable of dealing with the increased formation of free radicals and keeping them at the level of the non-respiring cells.
However, until today it has not been possible to show a conclusive link between mitochondrial activity, the formation of free radicals and ageing.
Excessive free radicals can cause oxidative stress, which may lead to serious health problems like neurodegeneration, cancer, or cardiovascular disease. Antioxidants can help reduce the risk posed by ...
A free radical is created when an atom has an unpaired electron whizzing around the nucleus. Inside mitochondria, there is formation of such free radicals called reactive oxygen species.
Mitochondria are the main intracellular source of oxygen free radicals, which are very reactive and can harm cellular structures and DNA. Cells can repair typical levels of oxidative damage.
"Free radicals" generated by the cell's mitochondria are actually beneficial to healing wounds, according to scientists from UC San Diego.
Interestingly, pretreatment of cells with the cathepsin D inhibitor pepstatin A blocked the CD437-induced free radical formation and apoptotic effects, suggesting the involvement of cathepsin D.
Sulfur respiration in mammals A common sulfur metabolite having antioxidant activity appears to be formed with the help of an enzyme found in mitochondria, highlighting a potential area of ...
