1. This difference, or hypoxanthine phosphoribosyl transferase and the DXS255 locus. 2. Hypoxanthine is produced from adenine, xanthine from guanine.3. Hypoxanthine is also a spontaneous deamination product of adenine.4. Another origin of hydrogen peroxide is the degradation of adenosine monophosphate which yields hypoxanthine . 5. It contains hypoxanthine , lumbrofebrin, and lumbritin. 6. The selective culture medium is called HAT medium because it contains hypoxanthine , aminopterin and thymidine. 7. He is also credited with the discoveries of inositol and the purine derivative known as hypoxanthine . 8. This medium is supplemented with hypoxanthine , aminopterin and thymidine, hence the name HAT medium. 9. The " Pheretima aspergillum " worm, used in Chinese medicine preparations, contains hypoxanthine . 10. HGPRT is a transferase that catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate.
