Cysteine

Cysteine is a sulfur containing, non-essential amino acid.

Chemical Formula: C₃H₇NO₂S

Other names: 2-Amino-3-mercapto-propionic acid

Layman's explanation: Although cysteine is synthesized in the body, it can also be obtained from poultry, wheat, broccoli, eggs and garlic. Cysteine is well known for its aid in the detoxification of the human body as well as for protection of the liver. Additionally, this compound is an aid to the metabolism of biochemicals such as heparin, biotin, coenzyme A and glutathione. There is little data to affirm any side effects of overdose of cysteine, though insufficient levels of cysteine are thought to increase the risk of cancer in the uterus. Because cysteine is converted to N-acetyl-cysteine (NAC) to perform the majority of its useful functions, NAC is sold as the dietary supplement rather than cysteine alone.

Keywords: N-acetyl-cysteine, detoxification, taurine
