WebCystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH 2 CH (NH 2 )CO 2 H) 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. [1] WebCysteine plays a critical role in protein structure by virtue of its ability to form inter- and intrachain disulfide bonds with other cysteine residues. Most disulfide linkages are found in proteins destined for export or residence on the plasma membrane. Why is …
