  1. Free Radicals and its effects to the Body By Daivik Gandhi

  2. Background • Cell  many molecules  one of more atoms of one or more elements • Atoms = Protons + Neutrons + Electrons • Chemical behaviour is determined by the number of electrons in its outer shell.

  3. Free Radicals - Background • Free Radicals are atoms or molecules which contain unpaired electrons. • Usually initiate chain reactions. • Free Radicals are not ions.

  4. Free Radicals and Cells • ‘The radical concept of ageing!’ • Energy release from food. • Energy release can also initiate cell damage. • Cells are affected by this.

  5. Free Radicals and DNA • DNA is made up of: G-C A-T • If a free radical enters a cell, it can cause damage to DNA. • When DNA replicates it may cause

  6. Free Radicals and the Heart • Free Radicals can also effect the heart by atherosclerosis • It is the oxidation of low density lipoproteins. • Then are covered by white blood cells to form an atheroma. • If/when it ruptures, it results in more cholesterol to be deposited on the artery walls which results in stenosis. • It could then lead to a thrombus forming  to an infarction.

  7. Where are Free Radicals • Free radicals are formed by the act of breathing. • Cigarette smoke, • high intake in low density lipoproteins. • Prescription drugs. • radiation • Rancid food • Alcohol • Stress • Even exercising.
