Cov ntawv thov tseem ceeb ntawm Hloov Kho Nucleosides

Taw qhia

Nucleosides, lub tsev thaiv ntawm nucleic acids (DNA thiab RNA), ua lub luag haujlwm tseem ceeb hauv txhua yam kab mob. Los ntawm kev hloov kho cov molecules, cov kws tshawb fawb tau qhib ntau yam ntawm cov ntaub ntawv muaj peev xwm hauv kev tshawb fawb thiab tshuaj. Hauv tsab xov xwm no, peb yuav tshawb txog qee qhov kev siv tseem ceeb ntawmhloov kho nucleosides.

Lub luag haujlwm ntawm Hloov Kho Nucleosides

Hloov kho nucleosides yog tsim los ntawm kev hloov cov qauv ntawm ntuj nucleosides, xws li adenosine, guanosine, cytidine, thiab uridine. Cov kev hloov kho no tuaj yeem cuam tshuam txog kev hloov pauv ntawm lub hauv paus, qab zib, lossis ob qho tib si. Cov qauv hloov pauv tuaj yeem muab cov khoom tshiab rau cov hloov pauv nucleoside, ua rau nws haum rau ntau yam kev siv.
