Rhamnose yog dab tsi?

Rhamnose yog ib qho txawv hauv qab zib uas pom muaj nyob hauv cov nroj tsuag thiab qee cov kab mob. Tsis zoo li feem ntau cov suab thaj, nws pom muaj nyob rau hauv ib qho L configuration es tsis txhob niaj hnub D configuration. Nws ua ib qho loj ntawm cov khoom cog ntawm phab ntsa thiab nws kuj yog txuam nrog lwm cov tebchaw, xws li phenolics. Hauv ib co kab mob gram tsis zoo, cov piam thaj yog khi rau lipids. Ob leeg cov ntshiab compound thiab lub lipid tivthaiv muaj ib tug xov tooj ntawm cov kev siv nyob rau hauv lub chaw ua tshuaj, kev ua liaj ua teb, thiab kev lag luam.

Ntxiv rau nws txawv L txawv zog, qhov no txawv txav yog qhov atypical vim hais tias nws yog ib qho kev lag luam deoxy. Xws li cov suab thaj yog feem ntau ntawm DNA lossis RNA. Cov paj nruag no pom muaj qab zib yooj yooj yim hauv qee cov nroj tsuag, tab sis feem ntau pom tau tias yog glycoside. Cov txheej txheem xws li muab sib xyaw kom haum nrog lwm cov paj xyuam, xws li phenolic.

 

Ib qho tseem ceeb thiab kev siv ntau hom qab zib hauv cov nroj tsuag yog ib qho khoom ntawm polysaccharides uas hu ua rhamnogalacturonans. Xws li cov kabmob polymers tseem ceeb heev rau kev cog ntoo ntawm cov khoom ua haujlwm thiab ua ib feem ntawm pectin, ib qho ntawm cov khoom uas muaj cog ntawm phab ntsa ua ke. Cov no yog ntev chains ntawm L-rhamnose tov nrog galacturonic acid. Muaj ntau hom mob rhamnogalacturonans uas sib txawv hauv lawv cov qauv ntawm cov ceg ntoo thiab cov khoom, uas muaj xws li lwm yam suab thaj.
