Vibrational characterisation and biological activity of carnosine and its metal complexes.

The spectroscopic characterisation of free carnosine and its coordination compounds with Cu(II), Zn(II) and Co(II) ions are discussed. Raman and IR studies on metal-carnosine systems have been performed, obtaining a relationship between the vibrational spectra and the structure of the predominant species formed. The biological activity of free carnosine and of its complexes is briefly considered.
