The aerialoxidation of L-cysteinyl-L-cysteine in water at pH 8.5 has been investigated. The reaction products, monomericcyclic disulphide and parallel and antiparallel cyclic dimers, were fractionated by gel and thin layer chromatography. The relative yields of the products are independent of the type of the catalyst used and strictly obey equilibriumrelationships. The equilibrium constant for the
