Cystine, which is formed from two cysteine molecules joined together, is more stable than cysteine, but may not be absorbed as well. "Cys" redirects here. Most sulfenic acids enjoy only a fleeting existence, quickly undergoing disulfide bond formation or further oxidation to sulfinic (-SO 2 H) or sulfonic (-SO 3 H) acids. {{view.translationsData[trans_lang][0].vote_count}}, {{app.userTrophy[app.userTrophyNo].hints}}, {{view.translationsData[trans_lang][0].word}}, {{view.translationsData[trans_lang][0].username}}.
