2. Product Description:
Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine. It can be converted to cysteine by reduction and was discovered in 1810 but was not recognized as a component of proteins until 1899, when it was isolated from animal horn – it is particularly abundant in skeletal and connective tissues, hair and digestive enzymes.
L- Cystine helps strengthen the immune system, reduce damage from free-radicals, repair RNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine. L-Cystine aids in preventing the side effects of chemotherapy and radiation. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow. L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age spots.
The cystine formation reaction starting from cysteine is the following one:Formation reaction of cystine starting from cysteine.The reaction starts with two cysteine molecules. When the reaction has finished, it produces a cystine molecule and also 2 protons (H+) and 2 electrons (e-), due to the disulfide bond that is formed between the two sulfurs of the two cysteines.
Product name L-Cystine
