Cystine

Other names: Cysteine

Cystine, also known as cysteine, is one of the most important amino acids in the human body. It is a stable and less reactive form of cysteine that is formed by a chemical reaction called oxidation, where two cysteine molecules combine to form one cystine molecule. Cystine is crucial for the formation of proteins, which are the basic building blocks of the human body. In addition, it plays an important role in the formation of skin, hair and nails, as well as in wound healing, detoxification or defence against bacteria and viruses.

Its further importance lies in industry and especially in food and pharmaceuticals. Cystine is used as a food additive, especially in dietary supplements, and as an ingredient in some medicines. Its ability to promote growth and regeneration of the body makes it a valuable aid in the treatment of various health problems. As far as the cosmetics industry is concerned, cystine can be found in a number of hair and nail care products. In fact, this amino acid can help improve their structure and appearance. In the pharmaceutical industry, in turn, cystine is used as part of drugs designed to treat various metabolic disorders. For example, disorders associated with cell degradation or as an adjunct in the treatment of cancer. It is also a component of some dietary supplements designed to strengthen, replenish the body during convalescence or to support athletic performance.
