  • Toxicity 100,000 IU?
  • Supplement

10
Minerals
  • Essential for normal physiologic function
  • Coenzymes, biochemical reactions, alter
    electrical currents, open transport channels,
    muscle contractions, excretory, hormone immune
    function
  • Major Minor-Trace
  • 5 gms total, daily requirement100mg calcium,
    phosphorus, magnesium, potassium, sodium,
    chloride
  • Absorption
  • Amino acid chelate
  • Calcium/magnesium 2/1

11
Free Radical
  • Free radical is a cluster of atoms one of which
    contains an unpaired electron in its outermost
    shell of electrons
  • Oxygen, nitrogen sulfur
  • Reactive Oxygen Species (ROS)
  • Sources
  • Ionizing radiation Air pollutants Tobacco
    smoke Alcohol - Fried foods - Stress

12
ROS - Formation
  • Interaction of ionizing radiation
  • Natural bi-product of cellular respiration
  • Electrons passing down the respiratory chain
    leak away from the main path and directly reduce
    oxygen molecule to superoxide anion
  • Synthesized by enzymes in phagocytic cells
    neutrophils macrophages

13
ROS - Types
  • Hydrogen peroxide
  • Hypochlorite ion
  • Hydroxyl radical
  • Most reactive
  • Most damaging
  • Superoxide anion or Singlet Oxygen

14
ROS - Damage
  • Cell Membrane
  • Fatty acid side chain
  • Hydroxyl radical removes a hydrogen atom from one
    of the carbon atoms
  • A molecule of water, leaving an unpaired electron
  • React with oxygen forming a singlet oxygen
  • Begin chain reaction until two radical form a
    covalent bond linking the two
  • Deformed fatty acid chains damage cell membrane
    function
  • Mitochondria directly exposed during cellular
    respiration

15
ROS - Damage
  • Mitochondrial mutation
  • Hydroxyl radical
  • Attacks all deoxyribose gt breaks in DNA strand
  • Deaminate nucleotide gt Single nucleotide
    plymorphisms SNPs
  • Cumulative accelerated degradation of
    mitochondrial fucntion
  • Premature aging, cancer, neurodegenrative diseases

16
ROS - Benefit
  • Hydrogen peroxide necessary in synthesis of
    thyroxine
  • Macrophages neutrophils
  • Generate singlet oxygen that kills bacteria
  • Neutrophils
  • Generate hydrochlorite ions antiseptic
  • Chemotherapy Radiation

17
Antioxidants - Endogenous
  • Endogenous
  • Super Oxide Desmutase SOD
  • Converts 2 superoxide anion and 2 hydrogen
    molecules to 1 Oxygen and 1 hydrogen peroxide
  • Glutathione peroxidase
  • Converts 2 GSH 1 hydrogen peroxide to 1 GSSG
    2 water
  • Catalase
  • Converts 2 hydrogen peroxides into 2 molecules of
    water and 1 oxygen

18
