:Cystine
Description:
Cystine is a naturally occurring amino acid that is formed by the oxidation of two cysteine molecules, resulting in a disulfide bond between their thiol groups. It is classified as a non-polar, hydrophobic amino acid and plays a crucial role in protein structure and stability, particularly in the formation of disulfide bridges that help maintain the three-dimensional conformation of proteins. Cystine is typically found in proteins and is important for the structural integrity of keratin, which is a key component of hair, skin, and nails. The chemical formula for cystine is C6H12N2O4S2, and it has a molecular weight of approximately 240.32 g/mol. Cystine is soluble in water and has a slightly acidic nature, with a pKa value that reflects its ability to participate in acid-base reactions. In biological systems, cystine can be reduced back to cysteine, which is vital for various metabolic processes. Its presence is also significant in the context of certain diseases, as imbalances in cystine levels can lead to health issues such as cystinuria.

CAS:<p>DL-Cystine is a non-essential amino acid that is used as a medication to treat metabolic disorders. It is also used in polymerase chain reactions and for the treatment of infectious diseases, such as Aerobacter aerogenes, Helicobacter pylori, and Chlamydia pneumonia. DL-Cystine has been shown to bind to the enzyme glutamate decarboxylase, which converts glutamate into gamma-aminobutyric acid (GABA). It has also been shown to have a role in transcriptional regulation and in mitochondrial membrane depolarization.</p>Formula:C6H12N2O4S2Purity:Min. 95%Color and Shape:White Off-White PowderMolecular weight:240.3 g/mol3,3′-Disulfanediylbis(2-aminopropanoic acid)
