Animals and humans have similar evolutionary backgrounds. Specific elements play critical roles in the structures of proteins and the activities of enzymes. The purpose of this page is to outline some of the uses of elements in the structure of animals and humans and to illustrate why these elements are essential in the body and for optimal health. * Calcium (Ca)
Structure of bone and teeth. * Phosphorous (Ph)
Structure of bone and teeth. Required for ATP, the energy carrier in animals. * Magnesium (Mg)
Important in bone structure. Deficiency results in tetany (muscle spasms) and can lead to a calcium deficiency. * Sodium (Na)
Major electrolyte of blood and extracellular fluid. Required for maintenance of pH and osmotic balance. * Potassium (K)
Major electrolyte of blood and intracellular fluid. Required for maintenance of pH and osmotic balance. * Chlorine (Cl)
Major electrolyte of blood and extracellular and intracellular fluid. Required for maintenance of pH and osmotic balance. * Sulfur (S)
Element of the essential amino acids methionine and cysteine. Contained in the vitamins thiamin and biotin. As part of glutathione it is required for detoxification. Poor growth due to reduced protein synthesis and lower glutathione levels potentially increasing oxidative or xenobiotic damage are consequences of low sulfur and methionine and/or cysteine intake. * Iron (Fe)
Contained in hemoglobin and myoglobin which are required for oxygen transport in the body. Part of the cytochrome p450 family of enzymes. Anemia is the primary consequence of iron deficiency. Excess iron levels can enlarge the liver, may provoke Diabetes and cardiac falurer. The genetic disease hemochromatosis results from excess iron absorption. Similar symptoms can be produced through excessive transfusions required for the treatment of other diseases. * Copper (Cu)
Contained in enzymes of the ferroxidase (ceruloplasmin?) system which regulates iron transport and facilitates release from storage. A structural element in the enzymes tyrosinase, cytochrome c oxidase, ascorbic acid oxidase, amine oxidases, and the antioxidant enzyme copper zinc superoxide dismutase. A copper deficiency can result in anemia from reduced ferroxidase function. Excess copper levels cause liver malfunction and are associated with genetic disorder Wilson's Disease * Manganese (Mn)
Major component of the mitochondrial antioxidant enzyme manganese superoxide dismutase. A manganese deficiency can lead to improper bone formation and reproductive disorders. An excess of manganese can lead to poor iron absorption. * Iodine (I)
Required for production of thyroxine which plays an important role in metabolic rate. Deficient or excessive iodine intake can cause goiter (an enlarged thyroid gland). * Zinc (Zn)
Important for reproductive function due to its use in FSH (follicle stimulating hormone) and LH (leutinizing hormone). Required for DNA binding of zinc finger proteins which regulate a variety of activities. A component of the enzymes alcohol dehydrogenase, lactic dehydrogenase carbonic anhydrase, ribonuclease, DNA Polymerase and the antioxidant copper zinc superoxide dismutase. An excess of zinc may cause anemia or reduced bone formation. * Selenium (Se)
Contained in the antioxidant enzyme glutathione peroxidase and heme oxidase. Deficiency results in oxidative membrane damage with different effects in different species. Human deficiency causes cardiomyopathy (heart damage) and is known as Keshan's disease. * Fluorine (Fl)
* Cobolt (Co)
Contained in vitamin B12. An excess may cause cardiac failure. * Molybdenum (Mo)
Contained in the enzyme xanthine oxidase. Required for the excretion of nitrogen in uric acid in birds. An excess can cause diarrhea and growth reduction. * Chromium (Cr)
A cofactor in the regulation of sugar levels. Chromium deficiency may cause hyperglycemia (elevated blood sugar) and glucosuria (glucose in the urine). Rats have been shown to have improved growth on diets which contain other micro nutrients. These include: * Lead (Pb)
* Nickel (Ni)
* Silicon (Si)
* Vanadium (Vn)
These elements are all toxic at high levels. Source:http://www.csua.berkeley.edu/~wuhsi/elements.html

Transition metals play many roles in the human body. Some of these are: transport oxygen from lungs to cells, convert sugar, fats, and proteins into ATP, produce catalase. They are also used in the connective tissue and bones, immune system, reproductive system, and nervous system.
Transition elements are important because they have the ability to form stable complex ions. They are present within groups 3 to 12 in the Periodic Table.
Human bodies use a few transition metals like iron and copper. Proteins that contain iron help out with oxygen transport as well as electron transfer.
There are two very important metals found in the human body that help carry out biological processes. These metals are iron and zinc.

Oxygen is very much important for the human body. Oxygen plays a vital role in the breathing processes and in the metabolism of the living organisms.

Knowing the chemical reactions of drugs to the human body and mixing said drugs. To know how atoms work in our body and in the outside world
Alkaline earth metals in the body play a huge role in health. For instance, calcium is the fifth most abundant in the human body. You need calcium for strong bones.

Alkali metals are very important in the human body. Primarily, the are used in the transmitting of nerve impulses. Atoms of these metals and others create a small voltage across the membranes of cells. This voltage is used to transmit information.
The importance of vegetables in our diet is to help provide the human body with vitamins. The human body needs vitamins in order to function properly.
