L-cysteine, a sulfur amino acid to stimulate Detox

L-cysteine is what is known as a nonessential amino acid, meaning that can be synthesized by the body and is therefore not an essential element of their diet. Because it possesses a thiol side chain is hydrophilic amino acid called with an affinity for aqueous systems. For this reason, it is relatively highly reactive, it is an important component of many enzymes and proteins.
Although, after all, is not an essential amino acid deficiencies may occur in young and old, and also in people with certain metabolic diseases. Dietary sources include foods rich in protein such as chicken, turkey, pork, dairy products and vegetables such as cereals, broccoli, garlic and onion.
The biochemistry of the amino acid starts with another amino acid called serine, and methionine as well. This is the fist of homocysteine, which combines with serine to form cystathionine. This is then converted into cysteine and alpha-ketobutyrate. The thiol group is very reactive and cysteine gives its biological properties.
L-cysteine has antioxidant properties due to the thiol is very sensitive to redox reactions. However, its detoxifying effect on the body that the amino acid is mainly considered as a supplement. Therefore, these properties are considered first.
Cysteine can reduce the toxic effects of alcohol as a hangover or more severe liver damage. The byproduct of alcohol metabolism that does more damage and is responsible for most of the negative side effects of excessive consumption of alcohol is acetaldehyde. L-cysteine converts acetaldehyde into acetic acid more acceptable, and thus prevents the aldehyde having too much of a negative effect on their health and well-being. However, the results of these studies were the only animals, and the therapeutic effects of cysteine have not yet been tested in humans.
What has been tested and is known as L-cysteine is effective in the detoxification of heavy metals in the body. A common source of heavy metal toxicity of dental amalgam to mercury in the teeth. Although the Environmental Protection Agency (EPA) said in 1989 that dental amalgam is a hazardous substance under Superfund law, many people have them in the mouth.
The thiol group and L-cysteine has a high affinity for mercury and other heavy metals, as previously reported, a supplement can be used to rid your body of mercury in dental fillings containing mercury leachate. It can also be used to bind with copper, lead and cadmium. Lead and cadmium are particularly toxic to the human body, and although the lead is no longer used in pipes and paint, and cadmium in toys and paintings, there are still many resources available to these two heavy metals can lead to the detoxification of man.
A supplement of L-cysteine can be used to remove heavy metals from the body. Any protein that contains cysteine or join heavy metals like lead, cadmium, molybdenum, cobalt and mercury, and they can be excreted from the body in the usual manner. This direct involvement in the detoxification of heavy metals is a useful property of this amino acid.
Another application of detoxification of L-cysteine is directly involved in protecting cellular glutathione levels, and preventing the death of liver cells by acetaminophen poisoning. The latter is of particular interest to many people since acetaminophen is known as paracetamol, and since it is a drug freely available without prescription drug overdoses are not unknown. The result of an overdose is necrosis of liver cells, liver failure and eventual death.
The treatment of choice is N-acetylcysteine. If used within 10 hours of the overdose is extremely effective, and even 16-24 hours is better than other controls. It is believed that free acetylcysteine, when available to the liver, allows the synthesis of glutathione. Glutathione can keep the production of metabolites necessary for detoxification specific fifth of paracetamol / acetaminophen.
L-cysteine is also an essential element in the biosynthesis of coenzyme A, an enzyme essential for energy production from fats and carbohydrates. There is also a very important element of hair, which is produced commercially. Without an adequate supply of healthy hair growth L-cysteine is not possible.
There are several complementary uses of L-cysteine, including the treatment of bronchial diseases in which the amino acids can help to liquefy and remove mucus from the airways and lungs. It is also used to protect against side effects of cancer chemotherapy and medical treatments for excessive exposure to radiation.
However, there are some situations in which L-cysteine should be avoided whenever possible. Diabetics should not be used, or those suffering from cystinuria, in which large amounts of amino acids, including cysteine excreted in urine. L-cystine, incidentally, is formed by oxidation of L-cysteine.
Paradoxically, the amino acids is one of the hundreds of additives to snuff made by cigarette companies. Although, like most tobacco additives, their purpose is unknown, there are two possible reasons for inclusion. L-cysteine is an expectorant known, which could be added to promote expectoration of mucus in the lungs, which is favored by smoking, and also increases the production outside of the antioxidant glutathione is depleted in smokers.
There are several other non-medical uses for amino acids, but for their detoxification properties, it is used as a supplement. However, because it is largely derived from human hair or duck feathers, can not be classified as kosher or halal, despite many statements in this regard, while the most expensive source of microbial fermentation corn sugar can be.
The substance is recognized as safe by the FDA, and must be labeled as L-cysteine when present in a preparation for therapeutic effects. Note, however, that should be avoided by diabetics. Look at your store or food for the Internet amino acid L-cysteine.
