disease, exhaustion...) - What's common?
illnesses, exhaustion are all caused by
- oxidative stress by free radicals, and
Organisms age because cells accumulate free radical damage over time.
radicals... are everywhere around
us and constantly attack our bodies, causing aging and
deterioration. Free radical damage is oxidative damage.
Free radical damage within cells has
been linked to a range of disorders including cancer, arthritis,
atherosclerosis, Alzheimer's disease and diabetes.
DNA cross-linking can lead to various effects of aging, especially
Other cross-linking can occur between fat and protein molecules, which leads to
Free radicals can oxidize LDL and this is a key event in the formation of plaque in arteries, leading to
inflammation, heart disease and stroke.
Free radicals are atoms or
molecules that have a single unpaired electron on their outer
shell. Most free radicals are highly reactive in their
quest for electrons.
If their hunger is not satisfied, they
turn against the
human body and try to steal electrons from its own cells.
