Qhov sib txawv tseem ceeb ntawm adenosine thiab deoxyadenosine yog adenosine yog ribonucleoside uas muaj ribose qab zib moiety hauv nws cov qauv, thaum deoxyadenosine yog deoxyribonucleoside uas muaj deoxyribose qab zib moiety hauv nws cov qauv.
Nucleosides yog glycosylamines. Lub nucleoside muaj nucleobase (nitrogenous puag) thiab tsib-carbon qab zib. Raws li cov piam thaj moiety, nucleosides yog ob hom. Yog hais tias ib tug nucleoside muaj ribose qab zib moiety, nws hu ua ribonucleoside. Yog hais tias lub nucleoside muaj deoxyribose qab zib moiety, nws hu ua deoxyribonucleoside. Hauv nucleoside, cov pa roj carbon monoxide txuas los ntawm glyosidic daim ntawv cog lus rau N9 ntawm purine lossis N1 ntawm pyrimidine. Nucleosides hloov mus rau nucleotides thaum ib lossis ntau pawg phosphate khi rau lawv cov qauv. Nucleotides yog lub tsev blocks ntawm DNA thiab RNA. Adenosine thiab deoxyadenosine yog ob hom nucleosides uas muaj adenine nitrogenous puag.
Adenosine yog dab tsi?
Adenosine yog ribonucleoside uas muaj adenine nitrogenous puag thiab ribose qab zib moiety hauv nws cov qauv. Adenosine tsis muaj phosphate pawg. Cov molecule no muaj cov adenine txuas rau ribose qab zib moiety ntawm β-N9-glycosidic daim ntawv cog lus. Adenosine yog ib qho organic compound uas tuaj yeem tshwm sim hauv qhov xwm txheej.
Daim duab 01: Adenosine
Adenosine yog ib qho ntawm plaub lub tsev nucleoside ntawm RNA uas yog qhov tseem ceeb rau txhua yam kev ua neej. Ntxiv mus, nws cov derivatives suav nrog cov khoom siv hluav taws xob xws li adenosine mono, di, thiab triphosphate (AMP/ADP/ATP). Adenosyl (Ad) yog cov radical tsim tom qab tshem tawm ntawm 5 'hydroxyl (OH) pawg. Nws muaj nyob rau hauv vitamin B12 thiab radical SAM enzymes. Tsis tas li ntawd, adenosine kuj yog siv los ua tshuaj. Nws muaj txiaj ntsig zoo hauv kev kho mob ntawm supraventricular tachycardia (SVT). Nws kuj yog siv los ua ib qho ntxiv rau thallium myocardial perfusion scintigraphy (nuclear stress test) hauv cov neeg mob uas tsis tuaj yeem kuaj kev ntxhov siab txaus nrog kev tawm dag zog.
Deoxyadenosine yog dab tsi?
Deoxyadenosine yog deoxyribonucleoside uas muaj deoxyribose qab zib moiety hauv nws cov qauv. Nws txawv ntawm adenosine. Hauv qhov xwm txheej ntawm deoxyadenosine, pawg hydroxyl hauv cov piam thaj moiety ntawm 2 'txoj hauj lwm yog hloov los ntawm H atom. Qhov kev hloov no hloov ribose qab zib moiety rau hauv deoxyribose qab zib moiety. Nws kuj yog ib qho ntawm plaub nucleoside tsev blocks ntawm DNA. Cov tshuaj formula ntawm deoxyadenosine yog C10H13N5O3
Daim duab 02: Deoxyadenosine
Deoxyadenosine yog DNA nucleoside A uas ua ke nrog DNA nucleoside T (deoxythymidine) hauv ob-stranded DNA. Thaum tsis muaj adenosine deaminase (ADA), deoxyadenosine nyhav rau hauv T lymphocytes thiab tua cov hlwb. Cov txheej txheem no ua rau muaj kab mob caj ces hu ua adenosine deaminase hnyav ua ke tiv thaiv kab mob (ADA-SCID). Tsis tas li ntawd, nws muaj lub luag haujlwm ua tib neeg metabolite, Saccharomyces cerevisiae metabolite, Escherichia coli metabolite, thiab nas metabolite.
Dab tsi zoo sib xws ntawm Adenosine thiab Deoxyadenosine?
- Adenosine thiab deoxyadenosine yog ob hom nucleosides.
- Ob nucleosides muaj adenine nitrogenous puag.
- Cov nucleosides muaj qab zib moiety.
- Ob nucleosides tsis muaj phosphate pawg.
- Lawv yog cov organic tebchaw.
- Lawv yog cov tseem ceeb ntawm RNA thiab DNA.
Qhov txawv ntawm Adenosine thiab Deoxyadenosine yog dab tsi?
Adenosine yog ribonucleoside uas muaj ribose qab zib moiety hauv nws cov qauv, thaum deoxyadenosine yog deoxyribonucleoside uas muaj deoxyribose qab zib moiety hauv nws cov qauv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm adenosine thiab deoxyadenosine. Tsis tas li ntawd, adenosine yog ib qho ntawm plaub lub tuam tsev nucleoside rau RNA, thaum deoxyadenosine yog ib qho ntawm plaub lub tsev nucleoside rau DNA.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm adenosine thiab deoxyadenosine hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Adenosine vs Deoxyadenosine
Adenosine thiab deoxyadenosine yog ob hom nucleosides uas muaj adenine nitrogenous puag. Adenosine muaj ribose qab zib moiety hauv nws cov qauv, thaum deoxyadenosine muaj deoxyribose qab zib moiety hauv nws cov qauv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm adenosine thiab deoxyadenosine.
