How many nitrogen atoms are attached with cobalt in vitamin B12?

Vitamin B12 (cobalamin) consists of a central cobalt atom surrounded by a heme-like planar corrin ring structure (Figure 3), with the four pyrrole nitrogens coordinated to the cobalt.

Do vitamin B12 contains cobalt?

Answer: Cobalt is one of the components of vitamin B12, also known as cobalamin. Patients with allergic contact dermatitis who receive vitamin B12 replacement have been reported to experience a variety of cutaneous reactions, including chronic vesicular hand dermatitis, cheilitis and stomatitis.

Does cyanocobalamin contain cobalt?

Cyanocobalamin (commonly known as Vitamin B12) is a highly complex, essential vitamin, owing its name to the fact that it contains the mineral, cobalt. This vitamin is produced naturally by bacteria, and is necessary for DNA synthesis and cellular energy production.

What is the molar mass of riboflavin?

Riboflavin/Molar mass

How is vitamin B12 metabolized?

Vitamin B12 is reduced and converted in the body to two active coenzyme forms, deoxyadenosylcobalamin and methylcobalamin. Deoxyadenosylcobalamin is required for hydrogen transfer and isomerization of methylmalonyl CoA to succinyl Co A. This reaction is involved in both fat and carbohydrate metabolism.

Which bond is present in cyanocobalamin?

Coenzyme B12’s reactive C-Co bond participates in two types of enzyme-catalyzed reactions.

What is a Corrin?

Wiktionary. corrinnoun. a molecular species that contains four reduced pyrrole rings joined in a macrocycle by three -CH= groups and one direct bond; central to the cobalt containing vitamin cobalamin.

What is vitamin B12 as cyanocobalamin?

Cyanocobalamin is a man-made form of vitamin B12 used to treat low levels (deficiency) of this vitamin. Vitamin B12 helps your body use fat and carbohydrates for energy and make new protein. It is also important for normal blood, cells, and nerves.

Why does vitamin B12 have cobalt?

Cobalt, as a trace element, is essential for rumen microorganisms for the formation of vitamin B12. In the metabolism of mammals, vitamin B12 is an essential part of two enzymatic systems involved in multiple metabolic reactions, such as in the metabolism of carbohydrates, lipids, some amino acids and DNA.

What is cobalt?

Sources of Cobalt It is found in green and blue watercolors and crayons as well. Cobalt is very often present in metal-plated buckles and buttons because it is used as an oxidizing agent in electroplating. It is used in metal alloys, such as that used to make drills, other cutting tools, and machine parts.

What is B12 (cyanocobalamin)?

Cyanocobalamin (commonly known as Vitamin B12) is a highly complex, essential vitamin, owing its name to the fact that it contains the mineral, cobalt. This vitamin is produced naturally by bacteria, and is necessary for DNA synthesis and cellular energy production.

What is the percentage of cobalt in cyanocobalamin?

Cyanocobalamin (vitamin B12) contains 4.34\% cobalt by mass. What is the molar mass of cyanocobalamin, assuming that there is one atom of cobalt in every molecule?

How do you find the molar mass of cyanocobalamin?

You can use the molecular mass of Co with its percent composition to find the molar mass of cyanocobalamin. Percent cobalt by mass = 4.34\% To find the molar mass of one percent of the molecule, divide the atomic mass of Co by its percent of total composition.

What is the percent mass of cobalt in molar mass?

Percent cobalt by mass = 4.34\% To find the molar mass of one percent of the molecule, divide the atomic mass of Co by its percent of total composition. Dwayne is in hot water for his latest comments. The big companies don’t want you to know his secrets. What is a cobalt bomb, can it destroy life on earth?
