摘要: Abstract Spectra and stability constants of binary ternary complexes were derived from ESR spectra aqueous solutions Cu(2+), ATP the dipeptides gly-L-trp L-trp-gly. The as well is only slightly influenced by tryptophan side chain. Parameters affecting shape an spectum a Cu(II) complex in solution are discussed detail. A comparison several species reveals different influence electronic mobility contributions chain depending on position dipeptide. In complexes, spectral determined stronger binding ligand.
