Notes:
The results of theoretical investigations are reported concerning the possibility of impurity-type charge carrier production in proteins. The energy band structures of the periodic protein model polyglycine calculated with the aid of the ab initio Hartree-Fock crystal orbital method and corrected afterwards for long-range correlation effects are compared with the empty levels of glyoxal, methyl-glyoxal, acrolein, and croton-aldehyde, suggested recently by Albert Szent-Györgyi as possible acceptors against proteins. The comparison with previous supermolecule calculations shows that appreciable charge transfer can be expected to glyoxal, methyl-glyoxal, and acrolein from the polypeptides, while croton-aldehyde is probably less efficient in this relation.
