Power Point Presentation on Trace Element Cobalt

1. Cobalt
Discovered by Georg Brandt, a Swedish chemist, in 1739 while he was trying to
prove that the blue color in glass was not due to Bismuth
Cobalt is essential to humans as well as to animals. It is known as the main
constituent of cobalamin, also known as vitamin B12, that is basically cobalt’s
biological reservoir as an “ultra-trace” element. In ruminant animals, the
bacteria found in them convert cobalt salts into a compound that can only be
produced by the bacteria: is vitamin B12.
The cobalt atom in vitamin B12 is attached and surrounded to a deoxyadenosyl
group, methyl group, and a cyano group or hydroxyl group. The human body has
a need for cobalt that is not in the ionic form of the metal but rather, for a
performed metallovitamin which cannot be synthesized from a simple dietary
meal. Thus, the content of vitamin B12 of foods is essential is the overall human
nutrition

2. Food sources of cobalt
Foods that are highly rich
in cobalt include meat,
milk, green leafy
vegetables, liver, clams and
oysters. The USDA and
Canada’s Health Dietary
Reference recommends
that every individual needs
to have sufficient amount
of cobalt rich food daily.

4. Cobalt Function:
The activity and function of cobalt is essentially the same as vitamin
B12, hence, meaning that cobalt plays a major role in the process of
erythropoiesis, the process wherein erythrocytes or red blood cells
are produced.
Cobalt-60, a gamma source, is used to treat some cancers
Cobalt Deficiency Signs and Symptoms
A deficiency of cobalt is equivalent to a deficiency of vitamin B12
with symptoms of pernicious anemia, nerve disorders and
abnormalities in cell formation. However, these symptoms cannot
be treated with cobalt alone.

5. COBALT DOSAGE
HEALTH EXPERTS SUGGEST THAT ADULTS NEED AROUND 1.5 ΜG OF
VITAMIN B12 DAILY; THE DAILY B12 RDA IS 2.4 ΜG FOR ADULTS AND
ADOLESCENCES. TO DATE NO COBALT RDA HAS BEEN ESTABLISHED.
HOWEVER, EXCESSIVE DEFICIENCY OF COBALT IS KNOWN TO LEAS TO
CERTAIN HEALTH DISORDERS. WORLD HEALTH ORGANIZATION SOURCES
HAVE SUGGESTED A MINIMUM DAILY INTAKE OF 1 MCG
Over Dosage or Toxicity of Cobalt:
Toxic Concentration are greater than or equal to 5 nano grame /ml. Although
it is essential to have sufficient amount of cobalt intake, it can be a
disadvantage when this mineral is taken in excessively high levels. Having high
amount of cobalt can decrease the fertility in men and affect the heart,may
enlarged(Cardiomyopathy & Cogestive heart failure). When taken in a long
periods of time, cobalt can cause over-production of red blood cells, and
damage the heart muscles as well as the thyroid gland, Inceased activity in the
bone marrow.
