The unpaired Cys, residue 34, in albumin is unusual in having a thiol group with a pK <6 (7,10).
One of its mechanisms of action is believed to be the scavenging of free radicals through its free thiol group.

This cytolytic activity is modulated by a second plasma protein, [[Alpha].sub.2]-macroglobulin, and that activity appears to depend on the generation of a new free thiol group when [[Alpha].sub.2]-macroglobulin is activated by its reaction with proteases.
