However, Tuna's only drawback is for those who suffer from hyperuricemia or gout due to its content of purines which is transformed into uric acid by the body. |
This is the enzyme responsible for converting adenosine to inosine in the catabolism of the purines. |
The CDR makes cells put their ordinary activities on hold and instead switch on their defence systems, in reaction to high levels in the bloodstream of chemicals called purines. |
In comparison with the deamination of cytosine to uracil, the deamination of DNA purines is a minor reaction. |
Left-handed Z-DNA forms most readily in strands that contain sequences with alternating purines and pyrimidines. |
That is why researchers in Japan are now studying the choice of basic ingredients that are low in purines. |
