Some optical properties of diadenosine-5'-phosphates.
The absorption spectra, optical rotatory dispersion, and circular dichroism of a series of diadenosine-5'-phosphates, differing in the length of the phosphate bridge, indicate that in this set of compounds the adenine residues form an intramolecular stacked conformation. The differences in the optical properties suggest that this arrangement is different from that deduced by others for diadenosine-3',5'-monophosphate (ApA(3',5')) but is of comparable stability.
