Cysteine ​​(sau ua Cys lossis C) yog ib qho tseem ceeb ntawm proteinogenic amino acid. Nws yog tshaj ntawm cov codons UGU thiab UGC. Tus thiol sab saw hlau hauv cysteine ​​feem ntau koom nrog hauv cov tshuaj tiv thaiv enzymatic, ua nucleophile. Qhov thiol yog qhov ua tau yooj yim rau oxidization los muab cov disulfide derivative cystine, uas ua haujlwm ua lub luag haujlwm tseem ceeb hauv ntau cov protein. Thaum siv los ua cov khoom noj ntxiv, nws muaj Enumber E920.

L-cysteine ​​yog ze rau kev cystine. Ob lub lwg me ntawm cysteine ​​ua ib lub qauv ntawm cystine cystine. Cysteine ​​yog qhov tsis tshua ruaj khov thiab yooj yim ua cystine, thiab cystine tseem tuaj yeem raug txo rau cysteine. Ob qho no yog leej faj-muaj amino acids, uas muaj cov nyhuv ua rau tawv nqaij tsim thiab tshem tawm.
