Cystine
CYSTINE is a non-essential amino acid created when two cysteine molecules bond together. As with cysteine, cystine also has a high sulfur content.
A little cystine occurs free in blood, but the rest is utilized in protein formation, helping to hold proteins together as they travel around the body. Cystine has proven necessary for the healing of burns and wounds after surgery. It also promotes healing in such respiratory disorders as bronchitis and reduces the damage from emphysema. Sometimes, cystine is found in the kidneys and bladder as minute crystals called cystine calculus stones.
Cystine has detoxification properties that have proven to protect the body from the absorption of excess copper and against damage from alcohol and smoking. One report stated its effectiveness against the side effects of drinking, including hangovers and liver and brain damage. Cystine also plays an important role in the activity of the white blood cells, which fight disease. As part of the insulin molecule, cystine assists in supplying insulin to the pancreas needed for assimilation of sugars and starches. Since cystine is poorly absorbed in the body, oral supplements are of little value.
