Cobalt Cobalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes. There is no evidence of cobalt deficiency in human beings, and no evidence on which to base estimates of requirements for inorganic cobalt.obalt is a trace element mineral whose main function is in vitamin B12, although there are some cobalt-dependent enzymes.

Cobalt (II) nitrate Cobalt nitrate is the inorganic cobalt (II) salt of nitric acid, often with various amounts of water.It is more commonly found as a hexahydrate, Co(NO 3) 2 ·6H 2 O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.nhydrous cobalt(II) nitrate adopts a three-dimensional polymeric network structure, with each cobalt(II) atom approximately octahedrally coordinated by six oxygen atoms, each from a different nitrate ion. Each nitrate ion coordinates to three cobalts.

Vitamin Toxicity Symptoms Water-soluble vitamins are not stored in your body, but some of them -- like vitamin C and some B vitamins -- can cause toxicity too.Vitamin A is important in forming light receptors in the eye and maintaining cells on the surface of tissues throughout the body.itamin A toxicity causes headaches, rashes, coarse hair, hair loss, dry or peeling skin and cracked lips. It also increases the risk of osteoporosis -- thin bones -- and may rarely cause pseudotumor cerebri -- increased pressure in the head characterized by such symptoms as headaches, nausea and vision changes.

- Cobalt deficiency in ruminants leads to a vitamin B12 deficiency that is corrected with cobalt supplementation. Because monogastric animals do not have a bacterial population in the gut that can synthesize sufficient vitamin B12, cobalt supplementation is ineffective.

COBALT Humans have been using compounds of cobalt since at least 1400. The compounds were used to color glass and glazes blue. In 1735, Swedish chemist Georg Brandt (1694-1768) analyzed a dark blue pigment found in copper ore. Brandt demonstrated that the pigment contained a new element, later named cobalt.Cobalt is a transition metal, one of several elements found in Rows 4 through 7 between Groups 2 and 13 in the periodic table. The periodic table is a chart that shows how chemical elements are related to each other.or example, it is used in a test known as the Schilling test. This test is a method for determining whether a person's body is making and using vitaminB 12 properly. Two other isotopes of cobalt, cobalt-57 and cobalt-58, are used for the same purpose.

Cobalt-60 Cobalt-60, 60 Co, is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59 Co. Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case the incidentally produced 60 Co is largely the resu

Cobalt (II) chloride Cobalt(II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl 2. It is usually supplied as the hexahydrate CoCl 2 ·6H 2 O, which is one of the most commonly used cobalt compounds in the lab. The hexahydrate is purple, whereas the anhydrous form is sky blue.

Nutrition and healthy eating Vitamin D toxicity, also called hypervitaminosis D, is a rare but potentially serious condition that occurs when you have excessive amounts of vitamin D in your body. Vitamin D toxicity is usually caused by megadoses of vitamin D supplements — not by diet or sun exposure.

COBALT â THE VITAMIN B12 ELEMENT, A MALE AND SOMEWHAT TOXIC ELEMENT Because of toxicity, supplementation with cobalt should be avoided. It is also not usually needed, as it is found in most foods. Also use caution with vitamin B12 supplements. Vitamin B12 supplements can easily supply too much cobalt, which can be somewhat toxic.HAIR ANALYSIS NOTES. A hair cobalt level above about 0.003 mg% or about 0.03 ppm is associated with some cobalt toxicity, usually from taking a lot of vitamin B12. Cobalt can be one of the amigos.These are elements that can become oxides and irritants to the body when they are in a toxic form.ecause of toxicity, supplementation with cobalt should be avoided. It is also not usually needed, as it is found in most foods. Also use caution with vitamin B12 supplements. Vitamin B12 supplements can easily supply too much cobalt, which can be somewhat toxic.

Cobalt-60 Cobalt has been discussed as a salting element to add to nuclear weapons, to produce a cobalt bomb, an extremely dirty weapon which would contaminate large areas with 60 Co nuclear fallout, rendering them uninhabitable. In one hypothetical design, the tamper of the weapon would be made of 59 Co

Vitamin Toxicity VITAMIN D. Vitamin D and vitamin A are the most toxic of the fat-soluble vitamins. The symptoms of vitamin D toxicity are nausea, vomiting, pain in the joints, and loss of appetite. The patient may experience constipation alternating with diarrhea, or have tingling sensations in the mouth.

Vitamin Toxicity Fish-liver oils may contain more than 180,000 IU/g. The acute toxic dose of vitamin A is 25,000 IU/kg, and the chronic toxic dose is 4000 IU/kg every day for 6-15 months. (Beta-carotene [ie, provitamin A] is converted to retinol but not rapidly enough for acute toxicity.)

-   It is a tough, lustrous silver-white magnetic metallic element that  is related to and occurs with iron and nickel and is used  especially in alloys.     In nutrition, cobalt is a trace mineral that forms part of the  structure of vitamin B12.The total amount of cobalt in your body  is 1.1 mg. It is readily absorbed from your small intestine, and  your liver stores most of your body's cobalt.    Cobalt is essential to humans as well as to animals.It is the main  constituent of cobalamin, also known as vitamin B12, that is  basically cobalt's biological reservoir. The activity and function  of cobalt is essentially the same as vitamin B12.   In nutrition, cobalt is a trace mineral that forms part of the  structure of vitamin B12. The total amount of cobalt in your body  is 1.1 mg. It is readily absorbed from your small intestine, and  your liver stores most of your body's cobalt.

Cobalt Today, some cobalt is produced specifically from various metallic-lustered ores, for example cobaltite (Co As S), but the main source of the element is as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo and Zambia yields most of the cobalt mined worldwide.obalt is the active center of coenzymes called cobalamins, the most common example of which is vitamin B12. As such it is an essential trace dietary mineral for all animals. Cobalt in inorganic form is also an active nutrient for bacteria, algae and fungi.

What Is Methyl B-12? The vitamin's form depends on the type of molecules attached to the cobalt. In methyl B-12, or methylcobalamin, the cobalt is connected to a specific structure of molecules called a methyl group. This group is responsible for its impact in the body. Only two forms of vitamin B-12 -- 5-deoxyadenosylcobalamin and methylcobalamin -- are metabolically active.

Cobalt poisoning Cobalt is a naturally occurring element in the earth's crust. It is a very small part of our environment and very small amounts are needed for many animals and humans to stay healthy. Cobalt poisoning can occur when you are exposed to large amounts of cobalt. There are three basic ways that cobalt can cause poisoning. You can swallow too much of it, breathe too much into your lungs, or have it come in constant contact with your skin.

- Cobalt is shiny, grey, brittle metal with a close packed hexagonal (CPH) crystal structure at room temperature but which changes at 421°C to a face centred cubic form. The metal is rarely used as a structural material in the pure form but almost always as an alloy or a component of another system.
