Qhov sib txawv tseem ceeb ntawm xanthine thiab hypoxanthine yog xanthine yog daim ntawv oxidized, hos hypoxanthine yog ib daim ntawv txo.

Xanthine cov ntaub ntawv los ntawm oxidation ntawm hypoxanthine. Yog li, xanthine muaj ob lub carbonyl carbon atoms thaum hypoxanthine tsuas muaj ib qho carbonyl carbon atom. Xanthine yog cov organic compound uas muaj cov tshuaj formula C5H4N4O 2 Ob leeg no yog cov organic tebchaw uas muaj ob lub nplhaib qauv.

Xanthine yog dab tsi?

Xanthine yog cov organic compound uas muaj cov tshuaj formula C 5H4N4O 2Nws yog purine puag. Peb tuaj yeem pom lub hauv paus purine no hauv ntau cov ntaub so ntswg tib neeg thiab cov kua dej. Peb kuj tuaj yeem pom qhov sib xyaw no hauv qee yam kab mob. Cov tshuaj no zoo li cov khoom dawb, thiab nws decomposes thaum cua sov. Cov molar loj ntawm xanthine yog 152.11 g / mol.

Daim duab 01: Cov Qauv Tshuaj ntawm Xanthine

Xanthine cov ntaub ntawv ua ib yam khoom ntawm txoj kev purine degradation. Muaj peb qhov kev tshwm sim loj uas tuaj yeem tsim xanthine; los ntawm guanine los ntawm guanine deaminase, los ntawm hypoxanthine los ntawm xanthine oxidoreductase, thiab los ntawm xanthosine los ntawm purine nucleoside phosphorylase.

Muaj ntau yam tseem ceeb siv xanthine. Piv txwv li, nws yog ib qho tseem ceeb raws li cov tshuaj precursor rau cov tshuaj, raws li ib tug tshuaj tua kab, raws li ib tug me ntsis stimulant, raws li ib tug bronchodilator, thiab lwm yam. Txawm li cas los xij, cov tshuaj no paub tias muaj tshuaj lom ntau dua.

Hypoxanthine yog dab tsi?

Hypoxanthine yog qhov txo qis ntawm xanthine. Yog li ntawd, peb tuaj yeem hu nws ua purine derivative. Nws ib txwm tshwm sim, thiab peb tuaj yeem pom nws ua ib feem ntawm nucleic acids. Hypoxanthine yog qhov txo qis ntawm xanthine. Xanthine tsim raws li oxidation ntawm hypoxanthine. Yog li ntawd, nws muaj ib tug carbonyl carbon, tsis zoo li xanthine (xanthine muaj ob carbonyl carbon atoms). Lub npe IUPAC yog hypoxanthine yog 1H-purin-6 (9H)-ib qho thiab cov molar loj yog 136.112 g / mol.

Daim duab 02: Cov qauv tshuaj ntawm Hypoxanthine

Hypoxanthine qee zaus pom muaj nyob hauv nucleic acid ua ib feem. E.g. hauv anticodon ntawm tRNA. Nws muaj nyob rau hauv daim ntawv ntawm inosine. Hypoxanthine muaj tautomer hu ua 6-hydroxypurine. Ntxiv mus, nws yog ib qho additive (nyob rau hauv daim ntawv ntawm ib tug nitrogen qhov chaw) nyob rau hauv tej lub hlwb, kab mob, kab mob cab. Tsis tas li ntawd, hypoxanthine yuav tsum muaj nyob rau hauv cov kab mob malaria parasite raws li qhov chaw rau nucleic acid synthesis thiab lub zog metabolism.

Hypoxanthine cov ntaub ntawv thaum xanthine oxidase enzyme ua rau xanthine. Nws kuj tsim raws li ib yam khoom ntawm spontaneous deamination ntawm adenine. Adenine zoo ib yam li cov qauv ntawm guanine. Yog li ntawd, qhov kev tsis txaus ntseeg no tuaj yeem ua rau muaj qhov yuam kev hauv DNA replication. Vim li no, hypoxanthine raug tshem tawm ntawm DNA los ntawm kev kho cov txheej txheem kho.

Qhov txawv ntawm Xanthine thiab Hypoxanthine yog dab tsi?

Qhov sib txawv tseem ceeb ntawm xanthine thiab hypoxanthine yog xanthine yog daim ntawv oxidized, hos hypoxanthine yog ib daim ntawv txo. Yog li, xanthine muaj ob lub carbonyl carbon atoms thaum hypoxanthine muaj ib carbonyl carbon atom. Ntxiv mus, molar mass ntawm xanthine yog 152.11 g / mol, thaum molar loj ntawm hypoxanthine yog 136.112 g / mol.

Tsis tas li ntawd, lwm qhov sib txawv ntawm xanthine thiab hypoxanthine yog xanthine muaj ob lub pa oxygen atoms hauv nws cov qauv tshuaj, thaum hypoxanthine tsuas muaj ib qho oxygen atom.

Summary – Xanthine vs Hypoxanthine

Xanthine thiab hypoxanthine muaj feem cuam tshuam rau ib leeg los ntawm kev siv tshuaj lom neeg; xanthine cov ntaub ntawv raws li oxidation ntawm hypoxanthine. Qhov sib txawv tseem ceeb ntawm xanthine thiab hypoxanthine yog xanthine yog daim ntawv oxidized, hos hypoxanthine yog ib daim ntawv txo. Yog li ntawd, xanthine muaj ob lub carbonyl carbon atoms thaum hypoxanthine muaj ib carbonyl carbon atom.
