Shining Loo of the XJTLU team. Many bioactive proteins and peptides have multiple disulfide bonds between cysteine amino acids, which are crucial for maintaining their precise 3D folded structure.

Disulfide bonds (RS-SR) are more stable than peroxide ... for instance in the oxidation of cysteine to sulfenic (R-SOH), sulfinic (R-SO 2 H) and sulfonic (R-SO 3 H) acids. Sulfur is also less ...
