Describe the effect of antioxidants on free radicals and show how this relates to atherosclerosis
Free radicals have the ability to oxidize the lipid fraction of lipoproteins when they enter into the cells lining the arteries. As a result, the lipoproteins, particularly LDL, become trapped in the cells with their load of cholesterol. In time, as this continues, a cascade of events follow that results in atherosclerosis. Antioxidants can help prevent or reduce the incidence of this oxidation and thus prevent or delay the occurrence of atherosclerosis.
