L-CYSTINE (for biochemistry) is a product provided by Research-Lab Fine Chem Industries. Laboratory reagents are chemicals which are used in laboratories as a part of experimental procedures. These reagents can be important parts of chemical reactions, analytical reagents or starting material for the production of other materials.

This L-CYSTINE is meant for biochemistry and is of laboratory grade. This compound is the oxidized dimer form of the amino acid, cysteine. It is slightly soluble in water. Cystine is obtained from the oxidation of two cysteine molecules, by the formation of a disulfide bond. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. L-Cystine has a variety of applications in chemical and biological sectors. This compound finds several applications in the synthesis of various organic derivatives. Cystine acts as a substrate for the cystine-glutamate antiporter, the transport system of which, increases the concentration of cystine inside the cell. Cysteine supplements are often marketed as anti-aging products for the claimed purpose of improving skin elasticity. It is generally incorporated in various culture media such as for studies of auxotrophs. This reagent is suitable for industrial synthesis of products and research applications.
