Abstract
Abstract Guanosine-5′-phosphate crystallizes from neutral solutions of NaCl in bundles of hair-like crystals. Dried bundles of these crystals give a fiber-like X-ray diffraction pattern which indicates that the monomers are arranged in a structure similar to the arrangement of residues in poly(rG). This arrangement consists of monomers grouped into tetramers which then stack upon themselves helically. A second type of diffraction pattern obtained from salt-free samples of guanosine-5′-phosphate is also noted.
