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...

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 increase significantly in spring. A remarkable decrease in the levels of the nucleosides triphosphates adenosine 5'-triphosphate (ATP) and guanosine 5'-triphosphate (GTP) was found in spring; correlatively, an increase in the levels of adenosine 5'-monophosphate (AMP) and guanosine 5'-monophosphate (GMP) and adenosine 5'-pyrophosphate (ADP) and guanosine 5'-pyrophosphate (GDP) was observed. A notable increase in the amounts of uridine 5'-diphosphate-D-glucose (UDP-glocuse) was detected at the end of the period of low metabolism, which is coincident with a decrease in the level of glycogen, observed by other authors. 1976 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_NIS18662_v26_n6_p472_Maggese http://hdl.handle.net/20.500.12110/paper_NIS18662_v26_n6_p472_Maggese |
