WebNational Center for Biotechnology Information WebPairs of cysteine sulfhydryl groups are often linked by disulfide bonds (–S–S–) within or between polypeptide chains as the basis of native tertiary or quaternary protein structure. Typically, only free or reduced sulfhydryl groups (–SH) [rather than sulfur atoms in disulfide bonds] are available for reaction with thiol-reactive compounds.
WebDec 16, 2016 · Since disulfide bonds are relatively weak, some free sulfhydryl is generally found for each disulfide bond (1.5–5.6% for four investigated MAbs 50). Intrachain disulfide reduction in the variable region has been investigated in detail 49, 55-57. In one of these studies the ratio of free thiol versus intact disulfide was found to be around 1:5 49.
