Coenzymes are small organic non- protein molecules that carry chemical groups between enzymes. [1] Coenzymes are sometimes referred to as cosubstrates. These molecules are substrates for enzymes and do not form a permanent part of the enzymes' structures. This distinguishes coenzymes from prosthetic groups, which are non-protein components that are bound tightly to enzymes - such as iron-sulfur centers, flavin or haem groups. Both coenzymes and prosthetic groups are types of the broader group of cofactors, which are any non-protein molecules (usually organic molecules or metal ions) that are required by an enzyme for its activity. [2]In metabolism, coenzymes are involved in both group-transfer reactions, for example coenzyme A and adenosine triphosphate (ATP), and redox reactions, such as coenzyme Q10 and nicotinamide adenine dinucleotide (NAD+). Coenzymes are consumed and recycled continuously in metabolism, with one set of enzymes adding a chemical group to the coenzyme and another set removing it. For example, enzymes such as ATP synthase continuously phosphorylate adenosine diphosphate (ADP), converting it into ATP, while enzymes such as kinases dephosphorylate the ATP and convert it back to ADP. Coenzymes molecules are often vitamins or are made from vitamins. Many coenzymes contain the nucleotide adenosine as part of their structures, such as ATP, coenzyme A and NAD+. This common structure may reflect a common evolutionary origin as part of ribozymes in an ancient RNA world. Metabolism involves a vast array of chemical reactions, but most fall under a few basic types of reactions that involve the transfer of functional groups.[3] This common chemistry allows cells to use a small set of metabolic intermediates to carry chemical groups between different reactions.[4] These group-transfer intermediates are the coenzymes.

1. The Powerful Antioxidant Lipoid Acid
August 05, 2008
Why lipoic acid is good for you
Lipoic acid (also known as alpha-lipoic acid and thioctic acid) is a coenzyme which is present in the mitochondria of cells. Lipoic acid is an enzyme helper, which works with enzymes to produce energy by breaking down sugar (in the Krebs cycle).
Alpha-lipoic acid (ALA) is a powerful antioxidant which is both water and fat soluble. This means that lipoic acid can deactivate both water and fat soluble free radicals.
The body usually makes enough of its own lipoic acid, but if there is an excess then lipoic acid behaves like an antioxidant.

4. Beri Beri - it's causes, symptoms and treatment
April 16, 2008
What is Beri Beri?
Beriberi is a vitamin deficiency disease in which the body does not have enough thiamine (vitamin B1). Beriberi literally means "I can't, I can't" in Singhalese, which reflects the crippling effect it has on its victims. Thiamine serves as a coenzyme in the chemical pathway responsible for the metabolism of carbohydrates. Persons may become deficient in thiamine either by not ingesting enough vitamin B-1 through the diet or by excess use, which may occur in hyperthyroidism, pregnancy, lactation, or fever. Prolonged diarrhea may impair the body's ability to absorb vitami... (read more)

5. What are the Functions of Vitamin B12 (Cobalamins)
February 28, 2008
Functions
Three main enzymatic reactions regarding vitamin B12 have been noted to occur in humans. The first reaction requires methylcobalamin as a coenzyme in the conversion of homocysteine into methionine. This reaction occurs in the cytosol of the cell. The reaction is intrinsic to the production of tetrahydrofolate (THF). The production of THF is irreversible and requires vitamin B12, therefore, a B12 deficiency can trap folate in its methyl form (also known as the folate-methyl trap), which in turn affects purine and thymidylate synthesis.
A second set of reactions requiring B1... (read more)

8. Coenzyme Q10 And Heart Health
September 25, 2007
The heart is the most important muscle in our body, it's our life pump. It is one of the few organs that are expected to work continuously, without rest, for a lifetime.
The heart beats about 70 times a minute, 100,000 times a day and about 36 million times a year. It pumps the equivalent of 2,500 - 5,000 gallons of blood per day through approximately 60,000 miles (100,000 km) of blood vessels. During an average lifetime, the heart will beat more than 2.5 billion times.
Because of all that the heart muscle requires the highest level of energetic support at all times. And this is wher... (read more)

12. Benefits of Vitamin B5, Sources and Deficiency
February 04, 2007
Vitamin B5 is also known as pantothenic acid. Its name is derived from the Greek word pantos meaning "from everywhere," as small quantities of pantothenic acid are found in nearly every food. In its functional form, vitamin B5 gets combined with another small, sulfur-containing molecule to form coenzyme A (or CoA). This conversion allows vitamin B5 to participate in a wide variety of chemical and organic reactions. Coenzyme A is needed to carry out various metabolic functions, and for the generation of energy in the form of ATP from fats, carbohydrates and proteins. Roger J. Williams... (read more)

13. The Best Antioxidant Supplement
January 18, 2007
The best antioxidant supplement is not an additive at all. Brewed teas, especially those popular in Asian countries are said to process the highest degree of antioxidant. Much has been written about green teas and their health benefit but some researchers have found that an even rarer variety of white tea may be the best source of antioxidant tested so far. White tea is only made from the tea flowers and the most delicate leaves and was used for royalty in ancient Chinese ceremonies. Studies have found that tea is especially preventative of gastric and esophageal cancer. One drawback to us... (read more)

20. Alpha Lipoic Acid
March 01, 2006
Alpha Lipoic Acid (ALA; thioctic acid; lipoic acid) is a coenzyme that is a very potent antioxidant. A body exposed to free radicals becomes more susceptible to diseases such as diabetes and liver damage. ALA, sometimes called the "universal" antioxidant, holds the capacity to neutralize the effects of free radicals in both fatty and water-based environments. The prevention and cure achieved by ALA, by virtue of neutralizing free radicals, is worth the credit it has gained in the therapeutic market. The human body holds the positive ability to produce small amounts of ALA. The benefits of addi... (read more)
