WebMethionine has a thioether side chain, and cysteine 's contains a thiol group. These side chains exist as free thiols inside the cell, and are oxidised causing them to pair up and form disulphide bonds in an extracellular environment. Thiols are more reactive than hydroxyl groups and react easily with mercurails and heavy metal salts.
