In 1928, Schmidt (1) first described the presence of 5’-adenylic acid deaminase in muscle. He succeeded in separating this enzyme from adenosine deaminase and in isolating inosinic acid and ammonia as products of the reaction. He also reported that it specifically deaminated 5’-adenylic acid. In 1947, Kalckar (2) described two methods for the preparation of this enzyme and introduced a spectrop...

In the crystal structure of the title compound, C(8)H(5)FO(4), the complete molecule is generated by crystallographic twofold symmetry with two C atoms and the F atom lying on the axis. The mol-ecule is almost planar with the carboxyl group twisted with respect to the mean plane of the benzene ring by a dihedral angle of 2.01 (1)°. In the crystal, inter-molecular O-H⋯O hydrogen bonds and C-H⋯F ...
