Transcript

  • 1.  
  • 2.
    • BIOCHEMICAL FUNCTIONS:
    • It maintains Intracellular Osmotic pressure,acid base balance.
    • Involves in cardiac & skeletal muscle activities, Mainly K+ required in depolarization & contraction of Heart.
    • Involved proper transmission of Nerve Impulses.
    • Pyruvate kinase(of glycolysis) needs K+.
    • Involved in Biosynthesis of proteins.
  • 3.
    • Absorption is efficient(90%).
    • Normal Serum Potassium 3.5 – 5 meq/L (Cell contain 100 – 120 meq/L ).
    • Excretion is through urine, during absorption of Na+ there is obligatory loss of K+, Aldosterone increases K+ excretion.
  • 4.
    • DAILY REQUIREMENT AND SOURCES
    • Potassium Total body potassium is 3500 meq 75% in skeletal muscle.
    • Daily requirement 3-4 gm/day
    • Banana, Orange, Potato, beans, Liver etc. Rich Source is Tender coconut water.
  • 5.
    • Hypokalemia
    • Serum K+ less than 3 meq/L
    • Cushing syndrome
    • Renal tubular acidosis.
    • Metabolic alkalosis, Diarrhea & vomiting
    • In Diabetic coma treatment with Insulin & Glucose Diuretics.
    • Muscle weakness, Tachycardia ,Cardiac arrest.
  • 6.
    • Hyperkalemia
    • Renal failure
    • Addison’s disease
    • Severe dehydration.
    • Intravenous administration of fluids with excessive potassium salts.
    • Depression of CNS,
    • Bradycardia.
  • 7.
    • The adult body contains about 20g magnesium.
    • 70% is present in bones and 30% in soft tissue and body fluids.
    • 2-3mg/dl
    • 350mg/day
    • Cereals,nuts beans,vegetables,meat milk and fruits.
  • 8.
    • BIOCHEMICAL FUNCTIONS.
    • Bones and teeth
    • Cofactor for enzymes requiring ATP,Hexokinase,glucokinase,phosphofructokinase,adenylate cyclase etc.
    • Neuromuscular function.
  • 9.
    • ABSORPTION.
    • Specific carrier system
    • Large amounts of calcium,phosphate and alcohol diminish Mg absorption.
  • 10.
    • Mostly organic form.
    • Methionine,cysteine.cystin.
    • Proteins contain about 1% sulfur by weight.
  • 11.
    • BIOCHEMICAL FUNCTIONS.
    • Structural conformation and biological function of proteins.The disulfide linkages
    • (-S-S-) and sulfhydral groups(-SH).
    • Thiamin,biotin,lipoic acid,pantathenic acid.
    • Heparin,Chondroitin sulphate,glutathione,taurocholic acid etc,
    • PAPS in the synthesis of glycosaminoglycans,detoxification mechanism.
    • S-adenosylmethionine in transmethylation reactions.
  • 12.
    • EXCRETION
    • Oxidized to sulfate in the liver and excreted in urine.
    • Inorganic sulfate(80%),organic or conjugated or etheral sulfate(10%) and unoxidized (10%).
    • The unoxidized sulpfur is in the form of sulfur containing aminoacids and thiocynates.
  • 13.
    • Antioxidant activity.
    • Along with vitamin E prevents the development of hepatic necrosis and muscular dystrophy.
    • Involved in maintaining the structural integrity of biological membranes.
    • Se as SELENOCYSTEINE is an essential component of enzyme GLUTATHIONE PEROXIDASE ,Prevents the damage caused by the hydrogen peroxide.
    • Binds with heavy metals.
    • Organ meats are rich source of Se.
