Non-Essential - Glycogenic and Ketogenic, Un-charged, Hydrophilic - Sulfur-Containing
Cystine is an oxidized dimeric, absorbable form of cysteine, formed by linking two cysteine residues via a disulfide bond.
Cystine functions as an antioxidant and is a powerful aid to the body in protecting against radiation and pollution. It can help slow down the aging process, deactivate free radicals, neutralize toxins; aids in protein synthesis and presents cellular change. Cystine is necessary for the formation of the skin, which aids in the recovery from burns and surgical operations. Hair and skin are made up 10-14% Cystine.
Promotes a faster recovery from surgery/injury, and increases white cell activity in the immune system increasing resistance to disease. May help with respiratory problems such as bronchitis.
Protective against radiation, pollution, ultra-violet light and other causes of increased free radical production.
Essential in growth, maintenance, and repair of skin.
Key ingredient in hair.
Stimulates white blood cell activity necessary for disease resistance. Promotes healing from surgery and burns.
Precursor to the amino acid Taurine.
Precursor to Chondroitin Sulfate, the main component of cartilage.
One of the 3 main sulfur-containing amino acids, along with Taurine and Methionine.
Major constituent of Glutathione, an important tripeptide made up of Cystine, Glutamic Acid, and Glycine. Cysteine and Cystine are interconvertible. Two molecules of Cysteine make Cystine.
Cysteine when absorbed during digestion as cystine (two cysteine molecules linked by a disulfide bond) in the gastrointestinal tract is more stable than the free amino acid cysteine.
Cystine travels safely through the GI tract and blood plasma and is promptly reduced to the two cysteine molecules upon cell entry.
