Vitamin B is vital for the body mostly for the nerves and the brain and this as example of coenzyme is also much vital for making of the red blood cells. It is also used in people that has anemia, other condition and diabetes.

This as example of coenzyme is a cobalamin and different from the cyanobalamin in the cyano group and is thus replaced with the ethyl group. It is much of the as example of coenzyme that is are and has metal along with alkali bonds. It is same n physiology to that of vitamin B and this as example of coenzyme is red crystal in color.


It is a derivate of the folic acid and is a commonly termed compound to be THFA and is good as example of coenzyme. Tetrahydrofolate is the main active metabolite of dietary folate and vital as a coenzyme in reactions.

It is made from the dihydrogolic acid by the reduction of dihydrofolate. The reaction is much inhibited by the methotrexate. This as example of coenzyme along with the help of serine hydroxymethyltransferase is converted to 5,10 methylenetetrahydrofolate. There are many bacteria that are seen to use the synthetize.

Thus this as example of coenzyme makes it a good target center for the sulfonamide that shall compete with the PABA precursor. This is said to be a super example of coenzyme and also a cofactor for certain reactions mostly for the synthesis of the nucleic and amino acids. It also acts as a carrier molecule apart form being a good as example of coenzyme to make a certain molecule that is of no function to humans yet is there.

Coenzyme A

This example of coenzyme is noted for its use in the oxidation and synthesis of the fatty acids and then oxidation of pyruvate in TCA. Enzyme nomenclature abbreviations in parentheses represent mammalian, eukaryotic, and prokaryotic enzymes. 

All of the genomes that have been sequenced for the enzyme encoding trait uses this example of coenzyme as substrate and about almost 4% of the enzymes in the cell use it as well again as a substrate. It is also seen in humans but the biosynthesis of this example of coenzyme needs cysteine and adenosine triphosphate.

This example of coenzyme is much volatile and also serves much of the metabolic functions in both of the carbolic and anabolic paths. It is also used in the regulation of post translation and also regulation of the pyruvate dehydrogenase and carboxylase to get itself maintained and then support the partition of the degradation and this example of coenzyme.

B vitamins

There are mostly 8 in types along with being much vital to the body and also being water soluble vitamins along with Vitamin C. Though these vitamins share similar names, they are chemically compounds that are seen in foods.

This example of coenzyme has 8 of its complex being B1, B2, B3, B5, B6, B7, B9 and B12. They are thiamine, riboflavin, niacin, pantothetic acid, pyridoxine, biotin, folic acid and cobalamin respectively. They are termed to be example of coenzyme with each being much vital for the body by being useful in all way.

This example of coenzyme helps in having good health and also good being. It helps in getting the body to ale building blocks with this example of coenzyme having its direct impact on the energy level of how the brain tends to work and the cell methods. It shall help in preventing and support to good cell, growing RBC, energy level, eyesight. Appetite, muscle tone, nerve function.

S-adenosyl methionine

This example of coenzyme is called for its names in the commercial area like SAM-e, SAMe or also AdoMet and is linked with diet.

It is much involved in the methyl groups that helps in transfer of the aminopropylation and transsulfuration. It is an anabolic reaction that at least place in the whole body. There are more than about 40 methyl that are transferred from SAM known and also many other substrates are done so with this example of coenzyme.

This example of coenzyme is also seen in the bacteria and is bound by the roboswitch SAM that regulated the genes in the methionine or the biosynthesis of the cysteine. This example of coenzyme is vital for regulator of the tRna, DNA, immune response and also for methylation. This example of coenzyme also gels in breaking of bad materials in the body with leaving no effects.

Non-vitamin coenzymes typically aid in chemical transfer for enzymes. They ensure physiological functions, like blood clotting and metabolism, occur in an organism.

Adenosine triphosphate or ATP is an example of coenzyme that is an essential non-vitamin coenzyme. In fact, it is the most widely distributed coenzyme in the human body. It transports substances and supplies energy needed for necessary chemical reactions and muscle contraction.

To do this, ATP carries both a phosphate and energy to various locations within a cell. When the phosphate is removed, the energy is also released. This process is result of the electron transport chain. Without the coenzyme ATP, there would be little energy available at the cellular level and normal life functions could not occur. The vitamin-derived coenzyme NADH begins the process by delivering electrons.

Folic acid

Folate is the natural form of vitamin B9, water-soluble and naturally found in many foods. It is also added to foods and sold as a supplement in the form of folic acid; this form is actually better absorbed than that from food sources of 85%.

The Recommended Dietary Allowance for folate is listed as micrograms (mcg) of dietary folate equivalents (DFE). Men and women ages 19 years and older should aim for 400 mcg DFE. Pregnant and lactating women require 600 mcg DFE and 500 mcg DFE. This example of coenzyme has the chemical formula of C19H19N7O6. When the baby is developing early during pregnancy, folic acid helps form the neural tube.

“Folate” is an example of coenzyme for vitamin B9 refers to the many forms of folic acid and its related compounds, including tetrahydrofolic acid called the active form, methyltetrahydrofolate  which is the primary form found in blood and pteroylglutamic acid. Historic names included L. ⁠casei factor, vitamin Bc and vitamin M. Folate is especially important during periods of frequent cell division and growth.

Some proteins, however, generate and maintain a super oxidized form of the flavin cofactor, the flavin-N(5)-oxide. This is the similar example of coenzyme.

FAD can exist in four redox states, which are the flavin-N(5)-oxide, quinone, semiquinone, and hydroquinone. FAD is converted between these states by accepting or donating electrons. FAD, in its fully oxidized form, or quinone form, accepts two electrons and two protons to become FADH2.

Flavoproteins were first discovered in 1879 by separating components of cow’s milk. They were initially called lactochrome due to their milky origin and yellow pigment. It took 50 years for the scientific community to make any substantial progress in identifying the molecules responsible for the yellow pigment. Flavin adenine dinucleotide consists of two portions: the adenine nucleotide and the flavin mononucleotide bridged together through their phosphate groups.

Function of example of coenzyme

Minerals and the vitamins do play a good part in the catabolic and anabolic pathways that lead to getting the biomolecules synthesized.

This helps in having the lipids, the proteins, carbs, the co-factors and also the nucleic acids synthesized. Some of the function for example of coenzyme lie with it being a vitamin or minerals. Some example of coenzyme function is-

Vitamins as coenzyme

The metabolite form of vitamin A, the retinoic acid is an example of coenzyme and functions as the regulator of genes with being much vital.

Vitamin A as an example of coenzyme is vital for getting the cells grow in basic way. Vitamin K is also an example of coenzyme for the ones that are motile like that of the CO2 groups. There is also a group of carboxylic that is released having them bind to the calcium with this step being vital for the making of osteicalcin which is needed for bone building.

 It is also needed for making of the prothrombin that plays vital role in getting the blood coagulated. These are some of the example of coenzyme that are vitamins acting to be an enzyme or coenzyme and getting in to serve several functions as per its needed and availability. Some of the example of coenzyme might also be acting as cofactors as well or both.

Minerals as a function of example of coenzyme

Minerals can be of much use in the world of biology with some being catalyst and some being cofactors. Enzyme nomenclature abbreviations in parentheses represent mammalian, other eukaryotic, and prokaryotic enzymes respectively. 

The time when the minerals tend to act as example of coenzyme they do not mess with the substrate or its enzyme. They tend to accelerate the reaction of biochemical process between the substrate and the enzyme. When example of coenzyme act as mineral they become a portion of the structure or substrate.

This so formed structure of example of coenzyme is vital for the processing of all the biochemical reaction. Minerals that actually act as example of coenzyme or cofactors are selenium, molybdenum, manganese and magnesium. Some of them are iodine, calcium cobalt that acts as example of coenzyme being a non-enzymatic one with rets being iron and zinc acting as both.
