Fat-soluble Essential Vitamins
Vitamin Function Deficiencies Can Lead To Sources
Vitamin A (Retinol) Critical to the development of bones, teeth, and skin; helps maintain eyesight, enhances the immune system, fetal development, gene expression Night-blindness, skin disorders, impaired immunity Dark green leafy vegetables, yellow-orange vegetables fruits, milk, butter
Vitamin D Critical for calcium absorption for bone development and strength; maintains a stable nervous system; maintains a normal and strong heartbeat; helps in blood clotting Rickets, osteomalacia, immunity Cod liver oil, milk, egg yolk
Vitamin E (Tocopherol) Lessens oxidative damage of cells,and prevents lung damage from pollutants; vital to the immune system Deficiency is rare; anemia, nervous system degeneration Wheat germ oil, unrefined vegetable oils, nuts, seeds, grains
Vitamin K (Phylloquinone) Essential to blood clotting Bleeding and easy bruising Leafy green vegetables, tea

Minerals and Their Function in the Human Body
Mineral Function Deficiencies Can Lead To Sources
*Calcium Needed for muscle and neuron function; heart health; builds bone and supports synthesis and function of blood cells; nerve function Osteoporosis, rickets, muscle spasms, impaired growth Milk, yogurt, fish, green leafy vegetables, legumes
*Chlorine Needed for production of hydrochloric acid (HCl) in the stomach and nerve function; osmotic balance Muscle cramps, mood disturbances, reduced appetite Table salt
Copper (trace amounts) Required component of many redox enzymes, including cytochrome c oxidase; cofactor for hemoglobin synthesis Copper deficiency is rare Liver, oysters, cocoa, chocolate, sesame, nuts
Iodine Required for the synthesis of thyroid hormones Goiter Seafood, iodized salt, dairy products
Iron Required for many proteins and enzymes, notably hemoglobin, to prevent anemia Anemia, which causes poor concentration, fatigue, and poor immune function Red meat, leafy green vegetables, fish (tuna, salmon), eggs, dried fruits, beans, whole grains
*Magnesium Required co-factor for ATP formation; bone formation; normal membrane functions; muscle function Mood disturbances, muscle spasms Whole grains, leafy green vegetables
Manganese (trace amounts) A cofactor in enzyme functions; trace amounts are required Manganese deficiency is rare Common in most foods
Molybdenum (trace amounts) Acts as a cofactor for three essential enzymes in humans: sulfite oxidase, xanthine oxidase, and aldehyde oxidase Molybdenum deficiency is rare
*Phosphorus A component of bones and teeth; helps regulate acid-base balance; nucleotide synthesis Weakness, bone abnormalities, calcium loss Milk, hard cheese, whole grains, meats
*Potassium Vital for muscles, heart, and nerve function Cardiac rhythm disturbance, muscle weakness Legumes, potato skin, tomatoes, bananas
Selenium (trace amounts) A cofactor essential to activity of antioxidant enzymes like glutathione peroxidase; trace amounts are required Selenium deficiency is rare Common in most foods
*Sodium Systemic electrolyte required for many functions; acid-base balance; water balance; nerve function Muscle cramps, fatigue, reduced appetite Table salt
Zinc (trace amounts) Required for several enzymes such as carboxypeptidase, liver alcohol dehydrogenase, and carbonic anhydrase Anemia, poor wound healing, can lead to short stature Common in most foods
*Greater than 200mg/day required

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
