CAS 921-01-7: D-Cysteine

Description: D-Cysteine is an amino acid that serves as a building block for proteins and is characterized by its thiol (-SH) group, which imparts unique chemical properties. It is the D-enantiomer of cysteine, meaning it has a specific spatial arrangement of atoms that distinguishes it from its L-form, which is more commonly found in nature. D-Cysteine is less prevalent in biological systems but can be synthesized and utilized in various biochemical applications. It plays a role in redox reactions due to the reactivity of its thiol group, making it important in the formation of disulfide bonds and in cellular antioxidant defense mechanisms. D-Cysteine is soluble in water and exhibits a slightly acidic nature, with a pKa value that allows it to exist in both protonated and deprotonated forms depending on the pH of the environment. Its CAS number, 921-01-7, is a unique identifier that facilitates its recognition in chemical databases and literature. Overall, D-Cysteine is significant in research and industrial applications, particularly in the fields of biochemistry and pharmaceuticals.
