CAS 56-89-3: (-)-Cystine
Description:(-)-Cystine, with the CAS number 56-89-3, is a naturally occurring amino acid that plays a crucial role in protein structure and function. It is a dimeric form of cysteine, formed by the oxidation of two cysteine molecules, resulting in a disulfide bond between their thiol groups. This compound is characterized by its white crystalline appearance and is soluble in water, which facilitates its biological functions. (-)-Cystine is essential for the stability of protein structures, particularly in the formation of tertiary and quaternary structures due to its ability to form disulfide bridges. It is also involved in various metabolic processes and is important for the synthesis of glutathione, a key antioxidant in the body. In terms of its biological significance, (-)-Cystine is found in many proteins and is vital for maintaining the redox balance within cells. Its presence is particularly noted in keratin, which is a major component of hair, skin, and nails. Overall, (-)-Cystine is integral to numerous physiological processes and contributes to the structural integrity of proteins.
