Minerals
- –Naturally occurring
- –Inorganic
- –Homogenous
- –Chemical elements
- –Make up very small % of body
-
Calcium
- Role
- –Most abundant mineral in the body
- –≈99% stored in bone and teeth
- Integral part of bone structure
- Bone serves as a calcium reserve, releasing or removing calcium from the blood
-
Calcium
- –Calcium
- and phosphorous are essential to bone formation
Calcium phosphate salts crystallize on collagen forming hydroxyapatite crystals that add rigidity to bone
- During and after the bone strengthening processes, fluoride may displace the “hydroxy” part of the crystals, making fluorapatite
- –A mineral that resists bone-dismantling forces to = help maintain bone integrity
-
Calcium
- Most abundant
- Can find most of this mineral in your body
- Calcium in Body Fluids
- –≈1% of calcium is in the fluids that bathe and fill cells
- –Regulates the transport of ions across cell membranes; of particular import in nerve transmission
- –Helps maintain normal blood pressure
- –Essential role in blood clotting
- –Essential for muscle contraction and therefore heartbeat
- –Allows secretion of hormones, digestive enzymes, and neurotransmitters
- –Activates cellular enzymes that regulate many processes
-
Phosphorous
- Role
- –≈85% is combined with calcium in the crystals of the bone and teeth
- –Phosphorous salts are buffers
- –Part of DNA and RNA
- –Phosphorus compounds carry, store, and release energy in the metabolism of energy nutrients
- –Form part of phospholipids
- –Present in some proteins
-
Magnesium
- Barely qualifies as major
- Only ≈1 ounce is present in the body of a 135-pound person
- Over half in the bones
- The rest in muscles, heart, liver, other soft tissues
- Only 1% in body fluids
- –Critical to many cell functions
- Assists in the functioning of more than 300 enzymes
- –Release and use of energy from energy-yielding nutrients
- –Directly affects the metabolism of
- Potassium
- Calcium
- Vitamin D
-
Potassium
The principal positively charged ion inside the body’s cells
- Role
- –Maintenance of fluid balance
- –Maintenance of electrolyte balance
- –Maintenance of cell integrity
- –Maintenance of heartbeat
-
Chloride
- Major negative ion in the body
- Role
- -Accompanies sodium in fluids outside cells
- -Acids-base balance
- -Electrolyte
- -Component of hydrochloric acid
-
Sulfate
- Required for synthesis of many sulfur-containing compounds
- Certain antioxidants
- Thiamin
- Sulfur-containing amino acids
- –Help strands of protein assume their functional shape
- –Skin, hair, and nails
- Contain rigid proteins, which have a high sulfur content
-
Sodium
- Role
- –Fluid balance
- –Electrolyte balance
- –Maintenance of extracellular fluid balance
- –Acid-base balance
- –Muscle contraction
- –Nerve transmission
- –As blood sodium rises, thirst ensures that a person will drink water until sodium-to-water ratio is restored
- –The kidneys then excrete the extra water along with the extra sodium
-
The Trace Minerals
Zinc
Works with protein in every body organ, liberates Vitamin A from the liver, involved in immunity
Iron
Needed in hemoglobin and myoglobin, the protein transporters/carriers of oxygen in the blood and muscle
Iodine
needed for thyroxine, made by the thyroid, helps regulate metbolism, deficiency leads to goiter
-
The Trace Minerals
- Fluoride
- Forms decay-resistant fluorapatite in teeth
- Chromium
- Works with insulin to regulate glucose
- Copper
- Helps form hemoglobin and collagen
- Selenium
- Works with Vitamin E to prevent oxidation
-
Water
- –Can survive with other deficiencies for months or years
- –Can only survive a few days without water
- –In less than a day, a lack of water alters the body’s chemistry and metabolism
- Water is found in
- –Blood vessels
- –Cells
- –Chemical structure of cells, tissues, organs
Water participates in many chemical reactions
-
Water
- Delivers nutrients / removes waste
- Water is great solvent
- –Dissolves amino acids, glucose, minerals, etc. for transport
- –Fats travel with water-soluble proteins
- Water’s incompressibility
- –Enables it to act as a lubricant and cushion at joints
- –Cushions sensitive tissues such as the spinal cord and fetus
- –Lubricates the digestive tract, respiratory tract, and all tissues that are moistened with mucus
- –Fluid that fills the eye keeps optimal pressure on the retina and lens
- Water balance
- –Water intake needs to equal water loss
- –Otherwise dehydration or water intoxication can occur
- Water cleanses the body
- –Nitrogen wastes must be removed
- –Kidneys filter wastes from the blood and excrete them with water as urine
-
Water
sources of water can be found in food, liquids, made from metabolism.
-
Water
Ways our bodies lose water is by the skin, kidneys, feces, lungs
-
Cretinism
A condition of severely stunted physical and mental growth, deficiency in iodine
-
pH scale
- pH scale
- 0-6 acidic
- 7 neutral
- 8-14 basic
-
Osmosis
When dissolved particles are separated by a membrane of water flow to the side of greater dissolved particle concentration
-
Pica
Deficiency in iron, those with this may eat dirt, rocks, nonfoods
-
Hydrochloric Acid
Contains chloride, aids in protein digestion
-

Dehydration and Water Intoxication
- Dehydration- an abnormal loss of water from the body,
- especially fromillness or physical exertion
Water Intoxication- result when a dehydrated person drinks too much water without the accompanying electrolytes.
