'''Zisteina''' ('''Cys''') [[proteina|proteinen]] osagaia den [[aminoazido]] ez esentzialetako bat da. Azido 2-amino-3-sulfanilpropanoiko honen formula kimikoa HO<sub>2</sub>CCH(NH<sub>2</sub>)CH<sub>2</sub>SH da eta UGU eta UGC [[kodon]]en bidez adierazten da.
[[Molekula]] polarra da, hau da, [[ur]]etan disolbagarria eta bere albo katean [[sufre]] [[atomo]] bat du. [[Metionina]], aminoazido esentziala, da bere aitzindaria.
