Download WHAT ARE FREE REDICALS/OXIDANT PARICLES

WHAT ARE FREE
REDICALS/OXIDANT PARICLES
• FREE RADICALS OR OXIDANT PARTICLES
ARE INCOMPLETE, UNSTABLE
MOLECULES.
• MOLECULES ARE BASIC BUILDING
BLOCKS IN NATURE, SUCH AS OXYGEN,
FATTY ACIDS AND AMINO ACIDS.
• ELECTRONS HOLD MOLECULES
TOGETHER. NORMAL MOLECULES HAVE
ELECTRONS THAT ARE IN PAIRS.
OXYGEN MOLECULES
• OXYGEN MOLECULES HAS FOUR
ELECTRONS.
• SUPPOSE THE MOLECULE LOSES ON
OF ITS ELECTRONS….NOW WE HAVE A
FREE RADICLES.
• A FREE RADICAL IS A MOLECULES THAT
FOR ONE REASON OR ANOTHER IS
MISSING ON OF ITS ELECTRONS.
• THIS MAKES IT UNBALANCED AND
EXTREMELY REACTIVE WITH OTHER
MOLECULES.
THE DAMAGE
• THE FREE RADICAL WANTS TO REPLACE
ITS LOST ELECTONS.
• IT WILL ROB ONE FROM A SECOND
MOLECULES.
• THE ROBBED MOLECULES NOW NEEDS
AN ELECTRON, SO IT WILL ROB A THIRD
AND SO ON IN A CHAIN REACTION.
• EACH TIME THIS THEFT OCCURS THE
MOLECULES INVOLVED ARE DAMAGE.
ANTIOXIDANT THE HERO?
• FREE RADICALS ARE FORMED IN OUR BODIES ALL THE
TIME FROM THE NORMAL USE OF OXYGEN BY OUR
CELLS.
• THE BY PRODUCT OF OXYGEN USE IS FREE RADICAL
FORMATION.
• THE BODY CAN USUALLY PROTECT ITSELF WITH THW
ANTIOXIDANT SYSTEMS.
• ANTI OXIDANT SCAVENGE, QUENCH, OR NUTERALISE
THE FREE RADICALS.
• AS LONG AS THERE IS A BALANCE BETWEEN FREE
RADICALS IN THE BODY AND THE ANTIOXIDANTS
MOPPING THEM UP OUR BODY ARE DOING WELL.
WHAT HAPPENS IF LESS
ANTIOXIDANT IN OUR BODY?
• THE BODY WILL BE IN BIG TROUBLE.
• THE FREE RADICLES HIJACK NEEDED
ELECTRONS FROM OTHER MOLECULES.
• FREE RADICALS CAN BADLY DAMAGE
AND INJURE CELLS IN VARIOUS PARTS
OF THE BODY.
DAMAGE CELLS – HOW?
• FREE RADICALS CAN BURST THROUGH CELLS
AND CAUSE THE CELL TO MULFUNCTION.
• ONCE INSIDE THE CELL, FREE RADICALS CAN
DAMAGE EVEN THE DNA, EFFECTING FUTURE
GENERATIONS OF THESE CELLS AND PERHAPS
MAKING THE CELL CANCEROUS.
• IT IS BELIEVE THAT GRADUAL ACCUMULATION
OF FREE RADICAL DAMAGE OVER THE YEARS IS
RESPONSIBLE FOR AGING.
• NORMAL CELLS MAY BE DESTROYED, UNABLE
TO FUNCTION OR EVEN DIE.
OXYGEN AND FREE RADICALS !
• ANYTIME OUR BODY HAS AN INCREASED NEED
FOR OXYGEN, OR IS STRESSED PHYSICALLY
OR EMOTIONALLY, MORE FREE RADICALS ARE
PRODUCED.
• STUDIES ARE SHOWING ATHLETES HAVE A
GREATER NEED OF ANTIOXIDANTS DUE TO THE
RAPID OXYGEN TURNOVER (OXYGEN USED).
• THE STRESS OF INJURY, SURGERY, A VIRAL
INFECTION, OR ANXIETY CAN CAUSE THE
PROLIFERATION OF FREE RADICALS.
FREE RADICALS OVERLOAD
• FREE RADICALS BURST THROUGH THE CELL MEMBRANE.
• THE CELL MEMBRANE CAN BE DAMAGE. DISTROY CELL
FACTORIES.
• CELLS HAVE DEFENSE MECHANISM “LYSOSOME” A HIT ON
THIS STRUCTURE, CELLS WILL BE DAMAGED.
• DNA STANDS TO BE DAMAGE. AND CAN LEAD TO CANCER
AND OTHER DISEASES
• THE “ENERGY FACTORIES” OF THE CELLS
(MITOCHONDRIA) CAN BE DAMAGED. THIS SLOW DOWN
ALL OF THE ACTIONS OF THE CELL.
DAMAGE IMMUNE SYSTEM
* DAMAGE CELLS DISTROY “CELL I.D CARD.
THESE CELLS MAY BE IDENTIFIED AS
INVADER.
• CELL PROTEIN MEMBRANE DAMAGE CAN
RESULT IN AN AUTOIMMUNE REACTION.
• WE ARE LEFT WITH A CELL THAT IS VERY
WEEK. WHEN IT DIVIDES IT WILL BE
DUPLICATES OF THIS SICK CELL.
• THE CELLS FORM TISSUE, TISSUE FORMS
ORGAN AND FORM HUMAN BEING.
FREE RADICALS AND DISEASES
• FREE RADICAL DAMAGE TO CERTAIN CELLS
IN THE EYES CAN CAUSE CATARACTS.
• FREE RADICALS DAMAGE TO AN INSULIN
PRODUCING CELL IN THE PANCREASE, YOU
MIGHT GET DIABETES.
• DAMAGE TO THE NERVE CELLS COULD BEGIN
A DEGENERATIVE NERVE DISESE SUCH AS
MULTIPLE SCLEROSIS.
• DAMAGE TO THE DNA COULD RESULT IN
CANCER.
• DAMAGE TO THE CELL CAN BE VERY
DANGEROUS TO YOUR HEALTH.
