Question 2. While internal cysteine amino acid sidechains in proteins undergo oxidation to produce disulfide crosslinks that stabilize the protein structure after folding, solvent-exposed cysteine sidechains can remain in their reduced thiol form and serve as reactive nucleophiles (recall for instance Acyl Carrier Proteins involved in fatty acid biosynthesis or various oxidoreductase enzymes). The reactive thiol groups in proteins can be detected using Ellman's test, wherein the protein is reacted with a disulfide Ellman's reagent to form a new mixed disulfide and a 2-nitro-5-thiobenzoate (TNB) byproduct. Upon addition of base, TNB is deprotonated to form a dianion, which absorbs light in the visible region and can be detected using UV-Vis spectroscopy.
