What is S-ACETYLMERCAPTOSUCCINIC ANHYDRIDE?
General Description
S-Acetylmercaptosuccinic anhydride is an amine reactive reagent, containing a sulfhydryl group. The anhydride region opens up, when attacked by an amine nucleophile, forming amine linkage. However, during this ring opening reaction, a free carboxylate group is formed rendering the molecule negatively charged. Activity to proteins and conformation of the molecule us affected by the charge reversal.
