WebDec 30, 2024 · This is true not just of H-bonds, but of the more permanent (i.e. covalent) disulfide bonds as well. Looking at the hypothetical example polypeptide, the secondary structure of the N-terminal half may lead to the formation of a stable disulfide bond between the first cysteine and the second cysteine, but in the context of the whole … Web1. Reduced proteins have their disulfide bonds broken by reducing agents such as dithiothreitol (DTT) or beta-mercaptoethanol, resulting in the formation of two sulfhydryl (-SH) groups. This process results in a protein sample that contains only single polypeptide chains. On the other hand, unreduced proteins contain disulfide bonds that hold ...
