✦ Synopsis

The acid/base chemistry and the zinc complexation of the four dipeptides H-HisHis-OH, H-HisHis-OEt, Ac-HisHis-OH and Ac-HisHis-OEt were investigated by potentiometric methods. 1:1 (zinc:dipeptide) complexes prevail in solution, and those complexes that could be isolated on a preparative scale also have 1:1 compositions. The stability data confirm
