Tumor … Thiolates, 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 … See more In biochemistry, a disulfide (or disulphide in British English) refers to a functional group with the structure R−S−S−R′.
