Question | Answer |
---|---|
nucleoside= | base + sugar |
nucleotide= | base + sugar + phosphate |
nucleotides are converted to | nucleosides |
nucleosides are converted to | free bases |
free bases are converted to | common base xanthine |
xanthine is converted to | uric acid |
uric acid is | excreted |
degradation of pyrimidines | reverse of synthesis |
too much uric acid= | gout |
xanthine---> | uric acid (xanthine oxidase) |
allopurinal | drug that inhibits xanthine oxidase |
precursor purine for AMP and GMP | IMP |
precursor pyrimidine for CTP and TTP | UMP |
