CAS:349-46-2 | D-Cystine

D-Cystine is a dimer formed by two D-cysteine ​​molecules connected by a disulfide bond. Cystine is one of the important sulfur-containing amino acids in nature. Its disulfide bond structure makes it play an important stabilizing role in the tertiary and quaternary structures of proteins. Its D-configuration is an isomeric form of its enantiomers and has special research significance in biology and organic chemistry. It appears as white crystals or powder, slightly soluble in water, insoluble in ethanol and ether.

1. In organic chemistry, it is used as a chiral reagent or chiral inducer in the synthesis of sulfur-containing organic compounds or chemical reactions that require the introduction of disulfide bonds.
2. As a precursor for the synthesis of some drugs, it has potential pharmacological applications, such as in the development of antioxidants, anti-inflammatory drugs, and drugs for the treatment of certain metabolic diseases.
3. It is studied for the preparation of certain food and cosmetic additives to improve the stability, texture, and function of the product.

1. As a compound, it is relatively safe under normal use conditions.
2. Excessive intake or long-term high-dose use may cause some adverse reactions.
3. When using, you should pay attention to follow the correct dosage instructions and ensure that the product source is reliable, and avoid using expired or damaged products.
