Thiolate form
WebThiolates, not thiols, attack disulfide bonds. Hence, thiol–disulfide exchange is inhibited at low pH (typically, below 8) where the protonated thiol form is favored relative to the deprotonated thiolate form. (The pK a of a typical thiol group is roughly 8.3, but can vary due to its environment.). Thiol–disulfide exchange is the principal reaction by which disulfide … WebNational Center for Biotechnology Information
