ChEBI Name cystine ChEBI ID CHEBI:17376 Definition A sulfur-containing amino acid obtained by the oxidation of two cysteine molecules which are then linked via a disulfide bond. Stars This entity has been manually annotated by the ChEBI Team. Secondary ChEBI IDs CHEBI:4052, CHEBI:23513, CHEBI:14062 Supplier Information ChemicalBook:CB5242140, eMolecules:496171 Download Molfile XML SDF Find compounds which contain this structure Find compounds which resemble this structure Take structure to the Advanced Search Wikipedia License Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH2CH(NH2)CO2H)2. It is a white solid that is poorly soluble in water. As a residue in proteins, cystine serves two functions: a site of redox reactions and a mechanical linkage that allows proteins to retain their three-dimensional structure.
