Biochemistry 2 E3,2
Biochemistry 2 Palmer Exam 3 nucleotides & nucleic acids
| 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 |
