MODEL_NOTES= The pattern of breakdown is very different for the two types of nucletide bases, purines and pyrimidines. In the case of pyrimidines the ring is reduced and then opened, and with the exception of beta-alanine the nitrogen is removed by deamination and transamination as ammonia, which must ultimately be converted into urea. However, in the case of purines only the amino nitrogen outside the ring is removed as ammonia. The purine ring itself is oxidized to uric acid by xanthine oxidase and excreted. In humans and primates, the conversion of urate to allantoin occurs non-enzymatically by interaction with oxygen free radicals. free text=Biochemiscal Pathways - An Atlas of Biochemistry and Molecular Biology Edited by Gerhard Michal free text=Color Atlas of Biochemistry by Jan Koolman and Klaus-Heinrich Rohm free text=Human Metabolism by Ramsey Bronk
