L-Cystine
CAS:L-Cystine is a nonessential amino acid in humans. It is a sulfur-containing amino acid, which forms the cystine molecule with another L-cysteine molecule. Cystine has been shown to have antioxidant properties due to its redox potentials and ability to form disulfide bonds. L-Cystine can be synthesized by the enzyme ATP-binding cassette transporter using the redox potential of NADH. It also plays an important role in protein synthesis, as it is a component of many proteins, including those that are involved in neural death and bowel disease. L-Cystine has also been found to have physiological effects on the human body at levels that are not toxic.Formula:C6H12N2O4S2Purity:Min 98.5%Color and Shape:White PowderMolecular weight:240.3 g/molL-Cystine
