General Description
Cystine is the oxidized dimer form of the amino acid cysteine and has formula (SCH2CH(NH2)CO2H)2. It is a white solid that is slightly soluble in water. It serves two biological functions a site of redox reactions and a mechanical linkage that allows proteins to retain their 3-dimensional structure.
