vitamin B12 | chemical compound | Britannica.
Is vitamin B12 organic or inorganic?
Vitamin B12 is unique among all the vitamins in that it contains not only a complex organic molecule but also an essential trace element, cobalt.
Which category do the B vitamins belong to?
B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism and synthesis of red blood cells. Though these vitamins share similar names (B1, B2, B3, etc.), they are chemically distinct compounds that often coexist in the same foods.
Is B12 a mineral?
Introduction. Vitamin B12 is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement and a prescription medication. Because vitamin B12 contains the mineral cobalt, compounds with vitamin B12 activity are collectively called “cobalamins” .
What is vitamin B12 in biology?
Cobalamin; Cyanocobalamin. Vitamin B12, also called cobalamin, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy.
Why are vitamins called organic compounds?
A vitamin is an organic compound, which means that it contains carbon. It is also an essential nutrient that the body may need to get from food.
Are vitamins organic compounds?
Vitamins are organic substances that are generally classified as either fat soluble or water soluble. Fat-soluble vitamins (vitamin A, vitamin D, vitamin E, and vitamin K) dissolve in fat and tend to accumulate in the body.
Are vitamins organic or inorganic compounds?
Vitamins are organic substances, which means they’re made by plants or animals. Minerals are inorganic elements that come from soil and water, and are absorbed by plants or eaten by animals. Your body needs larger amounts of some minerals, such as calcium, to grow and stay healthy.
What is the scientific name of vitamin B complex?
Biotin (B7) Folate or folic acid (B9) Cyanocobalamin (B12)
What is vitamin B known as?
There are eight B vitamins — collectively called B complex vitamins. They are thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9) and cobalamin (B12).
Is potassium and B12 the same thing?
Vitamin B12 is a water-soluble vitamin, so any excess amount will exit the body through the urine. Thus, no adverse effects have been associated with excessive intakes of vitamin B12. Potassium is an alkali metal that contributes most of the positively charged ions inside human cells.
What mineral is part of vitamin B12 quizlet?
Vitamin B12, also known as cyanocobalamin, is a complex vitamin containing the mineral cobalt.
What is the generic name for vitamin B12?
Cyanocobalamin is available under the following different brand names: Vitamin B12, Nascobal, Athlete, Calomist, Cobalamin, Cobex, Crystamine, Prime, Rubramine PC, Vibisone, and Eligen B12.
What is one of the biochemical functions of vitamin B12?
Vitamin B12 is crucial to various bodily processes, including : normal functioning of the brain and nervous system. cognitive functioning (ability to think) formation of red blood cells and anemia prevention.
What makes vitamin B12 an organic compound?
Vitamins are organic compounds (meaning they contain Carbon) and they are vital nutrients that organisms require in limited amounts. Just like other essential nutrients, vitamins must be obtained from the diet since the organism can not make them (or can not make enough of them) for survival.
What biochemical reactions are dependent on vitamin B12?
Abstract. Vitamin B12, a cobalamin, is required for only two enzyme reactions in humans and animals: The conversion of methylmalonyl CoA to succinyl CoA and addition of a methyl group to homocysteine to form methionine.
What are vitamins in biochemistry?
Vitamins are vital micronutrients that cannot be synthesized endogenously or in insufficient amounts, and the principal means by which we get vitamins is through our diet. Vitamins can classify as water-soluble or fat-soluble. The fat-soluble vitamins include vitamins A, D, E, and K.
What are the classification of vitamins?
- Fat-soluble vitamins are stored in the body’s liver, fatty tissue, and muscles. The four fat-soluble vitamins are vitamins A, D, E, and K.
- Water-soluble vitamins are not stored in the body. The nine water-soluble vitamins are vitamin C and all the B vitamins.
What are the 4 main organic compounds?
Organic compounds essential to human functioning include carbohydrates, lipids, proteins, and nucleotides. These compounds are said to be organic because they contain both carbon and hydrogen.
What is supplement in chemistry?
Dietary mineral chemical supplements are the chemical elements required by living organisms, other than the four elements carbon, hydrogen, nitrogen, and oxygen present in common organic molecules. Examples include calcium, magnesium, potassium, sodium, zinc, and iodine.
What is the chemical nature of vitamins?
A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism.
Which nutrients are organic compounds?
The main organic nutrients include carbohydrates, proteins, lipids, and vitamins. Carbohydrates, proteins, and lipids are macromolecules that provide the body with energy.
In general, vitamins are coenzymes, or parts of enzymes, that function to assist a specific enzyme to catalyze (increase the rate of) a reaction. Some vitamins are fat soluble and others are water soluble. Fat-soluble vitamins are probably the most common vitamins for some people.
How do you identify organic and inorganic chemistry?
The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them. Almost all the organic compounds contain the carbon-hydrogen or a simple C-H bond in them.
What is organic or inorganic chemistry?
While organic chemistry is defined as the study of carbon-containing compounds, inorganic chemistry is the study of the remaining (i.e., not carbon-containing) subset of compounds.
