WebWhen denaturing agents are removed from a protein solution, the native protein re-forms in many cases. Denaturation can also be accomplished by reduction of the disulfide bonds of cystine—i.e., conversion of the disulfide bond (―S―S―) to two sulfhydryl groups (―SH). This, of course, results in the formation of two cysteines. sicko assignment
