D-Cystine

Description:
D-Cystine is a naturally occurring amino acid derivative 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 compound due to its sulfur-containing side chains. D-Cystine 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. It is often found in various biological systems and is important in the synthesis of keratin, a key structural protein in hair and nails. The compound is soluble in water and exhibits a relatively high melting point. In terms of its chemical reactivity, D-Cystine can undergo reduction to yield cysteine, which is vital for various metabolic processes. Its CAS number, 349-46-2, is used for identification in chemical databases and regulatory frameworks. Overall, D-Cystine is significant in biochemistry and molecular biology, contributing to the understanding of protein folding and stability.
