WebJan 1, 2013 · 1.2 The Biological Chemistry of Thiols The cysteine side chain is generally considered the most potent nucleophile of all amino-acid side chains under physiological conditions. This notable level of reactivity is due to the presence of a thiol functional group. WebCysteine is a unique amino acid because its side chain contains a free thiol group that can react with another thiol (usually from another cysteine residue) to form a disulfide bond. If properly formed, disulfide bonds can stabilize proteins and promote stability. Thus, cysteine pairs can be introduced into proteins to form disulfide bonds in ...
