Ribose yog carbohydrate nrog tus qauv C5H10O5; tshwj xeeb, nws yog pentose monosaccharide (cov suab thaj yooj yim) nrog daim ntawv H− (C=O) - (CHOH) 4 − H, uas muaj tag nrho cov hydroxyl pawg nyob rau tib qho chaw hauv Fischer projection.

Lo lus xa mus rau ib qho ntawm ob tus enantiomers. Lo lus feem ntau qhia D-ribose, uas tshwm sim dav hauv qhov thiab tau tham ntawm no. Nws daim iav tsom iav duab, L-ribose, tsis pom nyob hauv xwm.

D-Ribose tau qhia thawj zaug thaum xyoo 1891 los ntawm Emil Fischer. Nws yog C' -2 carbon epimer qab zib D-arabinose (ob tus isomers ntawm uas muaj npe rau lawv qhov chaw, cov pos hniav arabic) thiab tus txha caj qaum nws tus kheej tau muaj npe raws li ib feem rov npaj ntawm cov tsiaj ntawv hauv lo lus [GG ] # 39; arabinose'.

Cov tawv nqaij β-D-ribofuranose ua ib feem ntawm caj qaum ntawm RNA. Nws cuam tshuam nrog deoxyribose, uas muaj nyob hauv DNA. Phosphorylated derivatives ntawm ribose xws li ATP thiab NADH ua si lub luag haujlwm hauv metabolism. cAMP thiab cGMP, tsim los ntawm ATP thiab GTP, ua tus xa xov thib ob hauv qee qhov kev taw qhia.
