Cysteine yog ib qho tsis tseem ceeb amino acid uas tuaj yeem tsim los ntawm tib neeg lub cev raws li lub cev muaj zog yog tias muaj cov methionine txaus. Cysteine feem ntau yog siv los ua tus thawj coj hauv kev lag luam khoom noj thiab tshuaj. Cysteine yog siv los ua kev pabcuam rau kev ci, ua ib qho ntxiv hauv cov luam yeeb, nrog rau kev npaj cov nqaij.
Propanoic acid, los yog cysteine, muaj sulfur-muaj amino acid ntawm txoj hauj lwm ob thiab ib pawg sulfanyl ntawm txoj hauj lwm peb. Nws ua haujlwm ntawm cov txheej txheem metabolite. Nws yog alpha-amino acid, polar amino acid, thiab amino acid uas muaj leej faj. Muaj ib pab pawg sulfanylmethyl hauv nws. Nws yog lub hauv paus conjugate ntawm cysteine. Nws yog cysteine (1-) conjugate acid. Nws yog cysteine zwitterion tus tautomer.
