Cysteine - Wikipedia

Structure Cystine is the disulfide derived from the amino acid cysteine. The conversion can be viewed as an oxidation: 2 HO2CCH(NH2)CH2SH + 0.5 O2 → (HO2CCH(NH2)CH2S)2 + H2O Cystine contains a disulfide bond, two amine groups, and two carboxylic acid groups. As for other amino acids, the … See more Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH2CH(NH2)CO2H)2. It is a white solid that is poorly soluble in water.
