Purine : Txhais

A tshuaj purine yog tsim los ntawm ib tug rau-tus tswv cuab nitrogen-muaj nplhaib thiab ib tug tsib-tus tswv cuab nitrogen-muaj nplhaib koom ua ke, zoo li ib tug hexagon thiab ib tug pentagon thawb ua ke. Purine cov hauv paus hauv DNA thiab RNA suav nrog adenine thiab guanine thiab yog li lub hauv paus paub zoo tshaj plaws ntawm qeb.

Hauv qhov no, lub ntsiab lus ntawm purine hauv biology yog dab tsi?

Kho mob Lub ntsiab lus ntawm Purine Purine : Ib qho ntawm ob chav kawm ntawm cov hauv paus hauv DNA thiab RNA. Cov tshuaj purine hauv paus yog guanine (G) thiab adenine (A). Uric acid, cov khoom ua txhaum cai hauv gout , yog a tshuaj purine khoom kawg.

Qhov thib ob, qhov ua haujlwm ntawm purine yog dab tsi? Ib qho tseem ceeb tshaj plaws luag hauj lwm purines pab yog nyob rau hauv kev tsim kho ntawm deoxyribonucleic acid (DNA) thiab ribonucleic acid (RNA). Ua khub cov purines thiab pyrimidines ua lub tsev blocks rau DNA.

Hauv qhov no, dab tsi yog purine hauv DNA?

Purines thiab Pyrimidines yog cov hauv paus nitrogenous uas ua rau ob yam sib txawv ntawm nucleotide hauv paus hauv DNA thiab RNA. Ob-carbon nitrogen nplhaib hauv paus (adenine thiab guanine) yog cov purines , thaum ib-carbon nitrogen nplhaib hauv paus (thymine thiab cytosine) yog pyrimidines.

Ib qho piv txwv ntawm purine yog dab tsi?

Piv txwv ntawm cov purines xws li caffeine, xanthine, hypoxanthine, uric acid, theobromine, thiab nitrogenous bases adenine thiab guanine. Purines ua haujlwm zoo ib yam li pyrimidines hauv cov kab mob.
