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. WebAn increase in stability of the native structure resulting from the formation of a particular disulfide bond has been said to be directly proportional to the number of residues between the linked cysteines, i.e. the larger the number of residues in the ‘disulfide loop,’ the greater the stability provided to the native structure. 22
