Concentration and seasonal variations of purine bases, nucleotides and nucleotide-sugars in liver of Bufo arenarum. Comparison with early embryogenesis

A comparative study of the bases, nucleotides and nucleotide-sugars was performed in liver of Bufo arenarum. Samples were obtained at different seasons of the year, according to the periods of active (December-March) and passive metabolism (April-July). It was found that guanine and hypoxanthine inc...
