Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage [goid 16209] [pmid 9685360] [evidence IDA]; Enables the directed movement of cholesterol into, out of, within or between cells.
